Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -4.294\% 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=C(Cn1nnc2ccccc2c1=O)NCCc1ccccc1
(b) Cc1ccc(C(=O)CSc2nc(N)cc(=O)[nH]2)cc1
(c) CCC(C)Sc1cc(C(F)(F)F)c(C(=O)Nc2ccc(Cl)cc2)cn1
Answer: a. O=C(Cn1nnc2ccccc2c1=O)NCCc1ccccc1
