Problem statement: Answer the multiple choice question.
Question: Which drug has a -1.458\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a O=c1[nH]cnc2cc(-c3ccccc3)sc12
b O=C(/C=C/c1ccccc1)Nn1cnc2ccccc2c1=O
c CC1(C)c2ccccc2N(CC(N)=O)C12C=Cc1ccccc1O2
d COc1cc(N)c(Cl)cc1C(=O)OCC(=O)NC1CCCC1
Answer: b. O=C(/C=C/c1ccccc1)Nn1cnc2ccccc2c1=O
