Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -4.123\% 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=c1[nH]c(=O)n(CCC2=CCCCC2)c(O)c1C=NCCCn1ccnc1
(b) CCOc1ccc(-c2cc3nc(C4CCN(C(=O)OC(C)(C)C)CC4)c(C(=O)O)cn3n2)cc1
(c) O=C(CSc1nnc(CNC(=O)c2ccccc2)o1)Nc1nccs1
Answer: a. O=c1[nH]c(=O)n(CCC2=CCCCC2)c(O)c1C=NCCCn1ccnc1
