Problem statement: Answer the multiple-choice question.
Query: Which drug has a 16.850\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] Nc1nnc(-c2ccc(Cl)cc2)s1
[b] O=C1C(Cc2ccccc2)S/C(=N/N=C/c2ccco2)N1c1ccccc1
[c] O=S(=O)(c1ccccc1)N1CCC(c2ccccc2)CC1
[d] CC(C)c1ccc(CN2CCSCC2)cc1
Answer: a. Nc1nnc(-c2ccc(Cl)cc2)s1
