Problem statement: Answer the MCQ question.
Query: Which drug exhibits a 9.980% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:

(b) O=C(OCc1nnc(-c2ccccc2)o1)c1cc([N+](=O)[O-])ccc1Cl
(c) CCC(c1nnc(SCC(=O)Nc2cccc(S(N)(=O)=O)c2)n1-c1ccc(OC)cc1)N(C)C
(d) CCOC(=O)C1=C(C)NC(=O)NC1C(C)C
Answer: b. O=C(OCc1nnc(-c2ccccc2)o1)c1cc([N+](=O)[O-])ccc1Cl
