Problem statement: Answer the multiple-choice question.
Question: Which drug has a -3.895\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: CC1CCC2(CC1)NC(=O)N(NC(=O)c1cccc(N(C)C)c1)C2=O
b: O=C(NCc1ccccn1)c1ccc(Br)s1
c: CC1CCN(C(=O)CSc2nc(=O)n3ccccc3n2)CC1
d: Cc1nn2c3c(cnc2c1-c1ccc(Cl)cc1)C(=O)CC(c1ccco1)C3
e: O=C(COC(=O)c1ccc(NS(=O)(=O)c2cccs2)cc1)NCC1CCCO1
Answer: b. O=C(NCc1ccccn1)c1ccc(Br)s1
