Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 13.668\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(CN1CCCCCC1)NCC1CCCO1.O=C(O)C(=O)O
(b) COc1cc(NC(=O)c2cc([N+](=O)[O-])ccc2Br)ccc1NC(=O)c1ccco1
(c) CCCn1nnnc1NCc1ccc(N(C)C)cc1
Answer: a. O=C(CN1CCCCCC1)NCC1CCCO1.O=C(O)C(=O)O
