Task: Answer the multiple-choice question.
Question: Which drug exhibits a 5.179\% 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(Cc1csc(Nc2nc(=S)[nH]c3ccccc23)n1)NCc1ccc(Cl)cc1
b COCCNC(=O)CN1C(=O)NC(c2ccccc2)(c2ccccc2)C1=O
c CC(C)NC(=O)NC(=O)COC(=O)c1ccc([N+](=O)[O-])cc1Cl
d COc1ccccc1OCc1ccc(C(=O)N(C)c2ccccc2)o1
e C=CCn1c(NCc2ccccc2OC)nc2ccccc21
Answer: b. COCCNC(=O)CN1C(=O)NC(c2ccccc2)(c2ccccc2)C1=O
