Task: Answer the multiple choice question.
Query: Which drug exhibits a -4.328\% 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 other words.
Options:
a) Cc1cccc(NC(=O)CSc2nnc(NC(=O)C3CC3)s2)c1C
b) COc1ccc(-c2nc(CSCC(=O)NC3CC3)c(C)o2)cc1OC
c) S=C(Nc1ccc(Br)cc1)NC1CCN(Cc2ccccc2)CC1
d) O=C(N/N=C/c1c(O)n(CCc2ccccc2)c(=O)[nH]c1=O)c1ccccc1O
Answer: d. O=C(N/N=C/c1c(O)n(CCc2ccccc2)c(=O)[nH]c1=O)c1ccccc1O
