Task: Answer the multiple choice question.
Question: Which compound exhibits a 20.443\% 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(N=C1SC2CS(=O)(=O)CC2N1Cc1ccccc1Cl)C1CCCO1
b. CC(C)(C)NC(=O)CSCc1ccc(Br)cc1
c. O=C(CSc1nnc(-c2c[nH]c3ccccc23)n1-c1ccc(F)cc1)NCc1ccco1
Answer: a. O=C(N=C1SC2CS(=O)(=O)CC2N1Cc1ccccc1Cl)C1CCCO1
