Task: Answer the multiple choice question.
Query: Which drug exhibits a 0.042\% 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 Cc1cccc(C)c1-n1cccc1/C=C1\SC(=S)N(c2cccc(C(=O)O)c2)C1=O
b CC(C)NS(=O)(=O)c1cccc2nsnc12
c O=c1c2ccccc2nc(-c2cccs2)n1-c1cnccn1
d CN(C)CCCCOc1cccc(Br)c1.O=C(O)C(=O)O
e Cc1cc(C(=O)NCc2cccnc2)no1
Answer: b. CC(C)NS(=O)(=O)c1cccc2nsnc12
