Task: Answer the multiple-choice question.
Question: Which drug exhibits a -18.854\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) CC(=O)c1nn(-c2cccc(Br)c2)cc1C(=O)c1ccc2ccccc2c1
b) CCN(CC)C(=O)/C(=C/c1ccc2c(c1)OCO2)NC(=O)c1ccc(Br)cc1
c) CCn1c(SCC(=O)OC2CCCCC2)nc2ccccc2c1=O
d) CCCCN(C(=O)CSCC(=O)Nc1ccc(C)cc1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
Answer: b. CCN(CC)C(=O)/C(=C/c1ccc2c(c1)OCO2)NC(=O)c1ccc(Br)cc1
