Task: Answer the multiple choice question.
Query: Which drug exhibits a 7.809\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) COc1cccc(NC(=O)c2oc3ccccc3c2NC(=O)C2CC2)c1
b) O=C1CCCC2=C1C(c1cccs1)Nc1ccccc1N2
c) COc1ccc(OCC(=O)Nc2c(Cl)ccc3nsnc23)cc1
d) COc1ccc(C(=O)/C=C/Nc2ccc(S(=O)(=O)Nc3nc(C)cc(C)n3)cc2)c(OC)c1
Answer: b. O=C1CCCC2=C1C(c1cccs1)Nc1ccccc1N2
