Task: Answer the multiple-choice question.
Question: Which drug exhibits a 3.345\% 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(CCNS(=O)(=O)c1cccs1)NCc1ccco1
b O=C(c1ccc2ccccc2c1)C1CCCN(C(=O)c2noc3c2CCCC3)C1
c CN1C(=O)C(C)(C)c2cc(S(=O)(=O)NCC3CCC(C(=O)NCc4ccc(F)cc4)CC3)ccc21
Answer: a. O=C(CCNS(=O)(=O)c1cccs1)NCc1ccco1
