You are given a geometric mathematical question. Questions in this task often involve shapes and Geometric 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.

Example Input: Which of the following could be the lengths of the sides of a triangle?
(A)3, 5 and 8 (B)3, 6 and 10 (C)4, 5 and 2 (D)5, 9 and 15 (E)10, 20 and 8
Example Output: C

Example Input: \begin{gather} nA = 360 \end{gather} The measure A, in degrees, of an exterior angle of a regular polygon is related to the number of sides, n, of the polygon by the formula above. If the measure of an exterior angle of a regular polygon is greater than 50 degrees, what is the greatest number of sides it can have?
(A)5 (B)6 (C)7 (D)8
Example Output: C

Example Input: Which of the following is the distance between the points (7, 3) and (11, 0) in the xy-coordinate plane?
(A)4 (B)5 (C)6 (D)7 (E)8
Example Output:
B
