Task: Answer the multiple choice question.
Query: Which drug exhibits a 3.996\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a O=C(O)CSc1nnc(CNc2ccccc2Cl)n1-c1ccccc1
b CCCCNC(=S)N(C)/N=C/c1ccc(F)cc1
c Cc1c(N)cc(N)cc1C(=O)O
d O=C(CN1C(=O)CCC1=O)Nc1ccc(Br)cc1
e CC1CCN(Cc2ccc(NC(=O)C3CCN(c4nnc(-n5cccc5)s4)CC3)cc2)CC1
Answer: d. O=C(CN1C(=O)CCC1=O)Nc1ccc(Br)cc1
