Task: Answer the multiple choice question.
Question: Which compound exhibits a 8.716\% 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, c, or d without using any additional words.
Options:
a: O=C1c2ccccc2C(=O)N1OCc1ccc(Cl)cc1
b: CCOC(=O)Cn1cnc2sc3c(c2c1=O)CCC3
c: Cc1csc(NC(=O)c2ccc(Br)s2)n1
d: CCC(C)(C)n1nnnc1C(c1ccccc1)N1CCN(C2CCCC2)CC1
Answer: a. O=C1c2ccccc2C(=O)N1OCc1ccc(Cl)cc1
