Task: Answer the MCQ question.
Question: Which drug has a 15.885\% 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(Nc1nnc(COc2ccc(Br)cc2)s1)c1ccco1
(b) Cc1cccc(C)c1NC(=O)Cn1cc(C=O)c2ccccc21
(c) COc1ccc(NC(=O)Cc2ccc(-c3ccccc3)cc2)cn1
(d) O=[N+]([O-])c1ccc(N2CCN(c3ccc(O)cc3)CC2)cn1
