Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 5.740\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a) O=C(Nc1cccc(Cl)c1)N1CCN(C2c3ccccc3-c3ccccc32)CC1
b) Cc1c(NCc2nc3ccccc3[nH]2)c(=O)n(-c2ccccc2)n1C.Cl
c) Cn1c(NCc2c[nH]c3ccccc23)nc2ccccc21
d) CC(=O)c1cccc(NC(=O)C2CC(=O)N(c3ccc4c(c3)OCCO4)C2)c1
e) O=C(N/N=C\c1ccco1)c1cncc(Br)c1
Answer: b. Cc1c(NCc2nc3ccccc3[nH]2)c(=O)n(-c2ccccc2)n1C.Cl
