Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 12.887\% 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: CC1(C)CC(=O)C=C(CN2C(=O)c3ccccc3C2=O)C1=O
b: O=C(Cn1c(C2CC2)nc2ccccc2c1=O)Nc1ccc(Br)cc1
c: CCCn1c2ccccc2c2cnn(CC(=O)NCCN(CC)CC)c(=O)c21
d: Cl.c1ccc(CN(CC2=NCCN2)c2ccccc2)cc1
e: CCCCN1C(=O)C(O)=C(C(C)=O)C1c1ccccc1[N+](=O)[O-]
Answer: b. O=C(Cn1c(C2CC2)nc2ccccc2c1=O)Nc1ccc(Br)cc1
