Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 20.418\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=S(=O)(NC1CCCCC1Nc1ccc(Cl)cc1)c1ccccc1
(b) COc1cccc(OCC(O)CN2CCN(C(c3ccccc3)c3ccccc3)CC2)c1.Cl
(c) O=C(COC(=O)/C=C/c1ccc(Br)o1)NC1CCCCC1
Answer: a. O=S(=O)(NC1CCCCC1Nc1ccc(Cl)cc1)c1ccccc1
