Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.488\% 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 additional words.
Options:
(a) Nc1ccc(-c2ccc(C(=O)O)s2)cn1
(b) CCOC(=O)N1CCN(c2c(NCc3ccccn3)c(=O)c2=O)CC1
(c) O=C1C[C@@H](c2ccc(O)cc2)Oc2cc(O)cc(O)c21
(d) COc1ccc(OC)c(C(c2c(C)[nH][nH]c2=O)c2c(C)[nH][nH]c2=O)c1
Answer: a. Nc1ccc(-c2ccc(C(=O)O)s2)cn1
