Task: Answer the MCQ question.
Question: Which drug exhibits a 14.605\% 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: CC(=O)c1cccc(NC(=O)CCS(=O)(=O)c2cc3c(cc2C)NC(=O)CO3)c1
b: O=C(O)C(NC(=O)c1ccccc1)=C(Cl)Cl
c: COCCNC(=O)COc1ccc(Br)cc1Cl
d: CCCCN=CC1=C(O)CC(c2ccccc2)CC1=O
e: O=C(OCc1ccc(Cl)cc1)c1cccnc1Cl
Answer: b. O=C(O)C(NC(=O)c1ccccc1)=C(Cl)Cl
