Problem statement: Answer the multiple choice question.
Query: Which compound has a 13.491\% 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) O=c1ccc(-c2ccccc2)nn1Cc1ccc(F)cc1Cl
b) COC(=O)C1CCN(C(=O)c2cc(-c3ccc(Cl)s3)nc3ccccc23)CC1
c) O=C(NCC1CC1)c1ccccc1Cl
d) CCN(CC)S(=O)(=O)c1ccc(C)c(NC(=O)/C=C/c2cccs2)c1
Answer: c. O=C(NCC1CC1)c1ccccc1Cl
