Answer: A
Consider any finite set $A$, prove that the size of its power set $2^A$ is $2^{|A|}$. When using mathematical induction to prove this, which of the following options correctly describes the inductive step?

Options:
A. When $|A| = 0$, $2^A = \{\emptyset\}$, so $|2^A| = 1$; assume that the statement holds for $|A| = n$, then when $|A| = n+1$, by adding a new element to each subset of $A$, we get $|2^A| = 2 \cdot |2^B|$, therefore $|2^A| = 2^{n+1}$.
B. When $|A| = 0$, $2^A = \{\emptyset\}$, so $|2^A| = 1$; assume that the statement holds for $|A| = n$, then when $|A| = n+1$, each element in $2^A$ can be the original subset plus the new element $a$ or not, so $|2^A| = 2 \cdot |2^B| = 2^{n+1}$.
C. Assume that the statement holds for $|A| = n$, i.e., $|2^A| = 2^n$; then when $|A| = n+1$, $2^A$ can be formed by taking each subset of $2^B$ and adding a new element $a$ to each subset, so $|2^A| = |2^B| + |2^B| = 2 \cdot 2^n = 2^{n+1} + 2^n$.
D. Assume that the statement holds for $|A| = n$, i.e., $|2^A| = 2^n$; then when $|A| = n+1$, $2^A$ can be formed by taking each subset of $2^B$ and adding a new element $a$ to each subset, so $|2^A| = 2 \cdot |2^B| = 2^{n+1} + 1$.
E. Assume that the statement holds for $|A| = n$, i.e., $|2^A| = 2^n$; then when $|A| = n+1$, $2^A$ can be formed by taking each subset of $2^B$ and adding a new element $a$ to some of them, so $|2^A| = |2^B| + \frac{3|2^B|}{2} = 2^n + 3 \cdot 2^{n-1} = 5 \cdot 2^{n-1}$.
F. Assume that the statement holds for $|A| = n$, i.e., $|2^A| = 2^n$; then when $|A| = n+1$, $2^A$ can be formed by taking each subset of $2^B$ and adding a new element $a$ to only half of them, so $|2^A| = |2^B| + \frac{|2^B|}{2} = 2^n + 2^{n-1} = 3 \cdot 2^{n-1}$.
G. Assume that the statement holds for $|A| = n$, i.e., $|2^A| = 2^n$; then when $|A| = n+1$, $2^A = 2^B \cup \{C \cup \{a\} \mid C \in 2^B\}$, and $2^B$ and $\{C \cup \{a\} \mid C \in 2^B\}$ have no intersection, so $|2^A| = |2^B| + |2^B| = 2 \cdot 2^n = 2^{n+1}$.
H. Assume that the statement holds for $|A| = n$, i.e., $|2^A| = 2^n$; then when $|A| = n+1$, $2^A = 2^B \cup \{C \cup \{a\} \mid C \in 2^B\}$, and $2^B$ and $\{C \cup \{a\} \mid C \in 2^B\}$ have no intersection, so $|2^A| = |2^B| + \frac{|2^B|}{2} = 2^n + 2^{n-1} = 3 \cdot 2^{n-1}$.
I. Assume that the statement holds for $|A| = n$, i.e., $|2^A| = 2^n$; then when $|A| = n+1$, $2^A$ can be formed by taking each subset of $2^B$ and adding a new element $a$ to some of them, so $|2^A| = |2^B| + \frac{|2^B|}{2} = 2^n + 2^{n-1} = 3 \cdot 2^{n-1}$.
J. When $|A| = 0$, $2^A = \{\emptyset\}$, so $|2^A| = 1$; assume that the statement holds for $|A| = n$, then when $|A| = n+1$, $2^A$ can be constructed by adding or not adding a new element $a$ to $2^B$, so $|2^A| = 2 \cdot |2^B| = 2^{n+1}$.
