Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.188% 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:
a. COc1ccc(C2Nc3ccccc3C(=O)N2NC(C)=O)cc1OC
b. COc1cc(NC(=O)c2cc([N+](=O)[O-])ccc2Br)ccc1NC(=O)c1ccco1
c. CCOC(=O)N1CCN(S(=O)(=O)c2c[nH]c(C(=O)OC)c2)CC1
d. CN(Cc1ccc2nonc2c1)Cc1nc(Cc2cccc(F)c2)no1
Answer: b. COc1cc(NC(=O)c2cc([N+](=O)[O-])ccc2Br)ccc1NC(=O)c1ccco1
