Task: Answer the multiple choice question.
Question: Which compound exhibits a 21.415\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) COc1ccc(C=O)cc1CN1CCCN(Cc2ccccc2F)S1(=O)=O
(b) O=C(CNC(=O)c1ccccc1)NCCc1nc2ccccc2[nH]1
(c) O=C(Nc1nnc(-c2ccncc2)s1)C1CCCO1
Answer: c. O=C(Nc1nnc(-c2ccncc2)s1)C1CCCO1
