You are given a mathematical question described with a circumscribed mathematical vocabulary. Questions in this task usually contain some variables (e.g. X, Y), equations (e.g. X+Y=3) and some relationships (X is greater than Y). Often you need to find the value of the variable using equations and relationships. You are also given 4 or 5 answer options (associated with "A", "B", "C", "D", "E"). Do not generate anything else apart from one of the following characters: 'A', 'B, 'C', 'D', 'E'. LaTeX mathematical format (the standard way to express mathematical expressions in the typesetting software known as LaTeX) is used to express equations. Each question is solvable with high school math knowledge. Give only one answer for each question.

Example Input: If \(2a + 4b = \sqrt { k } \), then \((a + 2b)\sqrt { k } \) =
(A)\(3k\) (B)\(2k\) (C)\(k\) (D)\(\frac { k } { 2 } \) (E)\(\frac { k } { 4 } \)
Example Output: D

Example Input: If \(x\) is an even number, then each of the following must be true EXCEPT
(A)\(2x + 7\) is odd (B)\(3x^2 + 5\) is odd (C)\(x^3 - x^2 + x - 1\) is odd (D)\(3x + 4\) is even (E)\((3x - 5)(5x - 3) is even\)
Example Output: E

Example Input: The first term of sequence I is 2, and each subsequent term is 2 more than the preceding term. The first term of sequence II is 2 and each subsequent term is 2 times the preceding term. What is the ratio of the 32nd term of sequence II to the 32nd term of sequence I?
(A)1 (B)2 (C)\(2^26\) (D)\(2^27\) (E)\(2^32\)
Example Output:
C
