Task: Answer the multiple choice question.
Query: Which drug exhibits a 15.479\% 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) CCOC(=O)c1c(N)sc(C(N)=O)c1C
(b) COc1ccc2cc(C(=O)C3CCCN(C(=O)CCc4ccccn4)C3)ccc2c1
(c) CC(=O)c1ccc(N2CCN(S(=O)(=O)c3cn(C)c(C)n3)CC2)cc1
(d) CCCn1nc(NS(C)(=O)=O)c2cc3cccc(C)c3nc21
Answer: a. CCOC(=O)c1c(N)sc(C(N)=O)c1C
