You are given a mathematical question described with an open-ended vocabulary. Questions in this task involve real-world situations, describing a mathematical problem. 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: A certain box contains only black, blue, and red pens. If a pen is chosen at random from the box, the probability of choosing a black pen is \(\frac { 1 } { 4 } \) and the probability of choosing a blue pen is \(\frac { 1 } { 6 } \). What is the probability of choosing a red pen?
(A)\(\frac { 1 } { 24 } \) (B)\(\frac { 1 } { 12 } \) (C)\(\frac { 7 } { 12 } \) (D)\(\frac { 3 } { 4 } \) (E)It depends on the number of pens in the box.
Example Output:
C
