Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 9.273\% 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=[N+]([O-])c1ccc(N/N=C/c2cccnc2)cc1
(b) COc1ccc(-n2nc(C(=O)NCC(=O)N3CCN(Cc4ccccc4)CC3)c3ccccc3c2=O)c(OC)c1
(c) Cc1cc(C)cc(NC(=O)C2CCN(C(=O)[C@@H]3Cc4ccccc4CN3)CC2)c1
(d) Cc1nc(CN2CCC(c3ccccc3)CC2)cc(=O)[nH]1
Answer: a. O=[N+]([O-])c1ccc(N/N=C/c2cccnc2)cc1
