Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.731\% 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 COc1ccc(C(=O)c2ccccc2)c(O)c1
b O=C(c1cc2c(ccc3ccccc32)oc1=O)N1CCN(CCO)CC1
c CCN1C=C(Cc2ccccc2C)C2=C(C1)C(c1ccccc1C)C(C#N)=C(N)O2.CCO
Answer: a. COc1ccc(C(=O)c2ccccc2)c(O)c1
