Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 21.761% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) O=C(CCS(=O)(=O)c1ccc(Br)cc1)N1CCC2(CC1)OCCO2
(b) O=C1NC(=O)N(c2ccccc2)C(=O)/C1=C\c1ccccc1[N+](=O)[O-]
(c) CC(=O)c1ccc(N(C(=O)Cc2c[nH]c3ccccc23)C(C(=O)NC2CCCCC2)c2cccs2)cc1
(d) O=C(CCN1C(=O)c2ccccc2C1=O)Nn1cnnc1
Answer: b. O=C1NC(=O)N(c2ccccc2)C(=O)/C1=C\c1ccccc1[N+](=O)[O-]
