Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.924% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CCc1nnc(NC(=O)CCC(=O)NCc2ccc(OC)cc2)s1
b: CSc1ccc2nnc(-c3cccc(F)c3)n2n1
c: O=C1CN(C(=O)/C=C/c2ccco2)c2ccccc2N1
d: O=S(=O)(NCC1CCCO1)c1cccc2nsnc12
Answer: a. CCc1nnc(NC(=O)CCC(=O)NCc2ccc(OC)cc2)s1
