Task: Answer the multiple choice question.
Query: Which drug exhibits a -4.530\% 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 additional words.
Options:
a) O=C1CC(c2ccccc2)NC(=O)N1
b) CC(=O)Nc1ccc(S(=O)(=O)N(C#N)c2nc(C)cc(C)n2)cc1
c) CCOC(=O)/C(=C\c1cccc(O)c1)c1nc2sc(C)c(C)c2c(=O)[nH]1
Answer: a. O=C1CC(c2ccccc2)NC(=O)N1
