Task: Answer the multiple-choice question.
Question: Which drug exhibits a 7.396\% 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 additional words.
Options:
a: Cc1nnc(SCc2cccc(Cl)c2)n(N)c1=O
b: O=[N+]([O-])c1ccc(Nc2nc(N3CCOCC3)nc(N3CCOCC3)n2)cc1
c: CCOc1cccc(C(=O)Nc2ccc(NC(=O)c3ccccc3)c(C)c2)c1
d: O=C(NC(=S)NCCCN1CCOCC1)c1ccc([N+](=O)[O-])cc1
Answer: a. Cc1nnc(SCc2cccc(Cl)c2)n(N)c1=O
