Task: Answer the multiple-choice question.
Query: Which drug exhibits a 9.503% 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(OC)c2c1sc(=NC(=O)c1cccc(N3C(=O)CCC3=O)c1)n2C
b: COc1ccc(-c2noc3c2-c2nc(-c4ccc(Cl)cc4)sc2CC3)cc1
c: Cn1c(=O)c(=O)n(C)c2cc(S(=O)(=O)CCC(=O)Nc3c(F)c(F)c(F)c(F)c3F)ccc21
d: CC(C)(C)NC(=O)CSc1nnc(-c2c[nH]c3ccccc23)o1
Answer: b. COc1ccc(-c2noc3c2-c2nc(-c4ccc(Cl)cc4)sc2CC3)cc1
