Task: Answer the multiple choice question.
Query: Which compound exhibits a 8.140\% 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: CC(C)CC(NS(=O)(=O)c1ccc2[nH]c(=O)c(=O)[nH]c2c1)C(=O)O
b: COc1ccc(OC)c(CCNC(=O)C2CCN(c3nnc(-n4cccc4)s3)CC2)c1
c: COc1ccc(S(=O)(=O)N2CCC(N3CCCCC3)CC2)cc1
d: O=C(CSc1nc2ccccc2[nH]1)Nc1ccc2[nH]c(=O)[nH]c2c1
Answer: d. O=C(CSc1nc2ccccc2[nH]1)Nc1ccc2[nH]c(=O)[nH]c2c1
