Task: Answer the MCQ question.
Query: Which drug exhibits a 3.695\% 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 COc1ccc(/C(=C\Nc2ccc(C)c(C)c2)C(C)=O)cc1OC
b Cc1ccc(-n2cc(C(=O)c3cc(Cl)ccc3O)cc(C#N)c2=O)cc1
c COc1ccc(C(O)(CCc2ccccc2)CCN2CCCCC2)cc1.Cl
d COC(=O)C1C(=O)/C(=C(/C)N2CCCC2)C(=O)CC1(C)C
Answer: a. COc1ccc(/C(=C\Nc2ccc(C)c(C)c2)C(C)=O)cc1OC
