Task: Answer the MCQ question.
Query: Which drug exhibits a -0.060\% human ether-à-go-go related gene (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 additional words.
Options:
a. COc1cccc(CNC(=O)C2CCCN(C(=O)c3ccc(Cl)cc3)C2)c1
b. CC(CNC1CCCCC1)OC(=O)c1ccccc1.Cl
c. COC(=O)c1cccc(NC(=O)/C=C/c2ccc([N+](=O)[O-])cc2)c1
d. CCn1c(/C(C#N)=C(\O)CCc2ccccc2)nc2ccccc21
Answer: d. CCn1c(/C(C#N)=C(\O)CCc2ccccc2)nc2ccccc21
