Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -0.331\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a COc1cc(C(=O)NCCc2ncccc2C)ccc1OC1CCN(C(C)=O)CC1
b O=C(COC(=O)c1cnccn1)Nc1cccc(S(=O)(=O)N2CCCCCC2)c1
c COc1ccccc1/C=C1\C(=O)Nc2ccccc21
Answer: b. O=C(COC(=O)c1cnccn1)Nc1cccc(S(=O)(=O)N2CCCCCC2)c1
