Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 2.189\% 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 O=C(Nc1ccccc1C(F)(F)F)c1ccccc1Br
b CC(C)CCc1c(O)nc(SCC(=O)N2CCCCCC2)[nH]c1=O
c Cc1nn(-c2cccc(C(F)(F)F)c2)c(=O)c2ccccc12
d Cc1cccc(Cn2c(N3CCN(CCO)CC3)nc3c2c(=O)[nH]c(=O)n3C)c1
Answer: a. O=C(Nc1ccccc1C(F)(F)F)c1ccccc1Br
