Task: Answer the MCQ question.
Query: Which drug exhibits a 3.156\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a CC(=O)NC1C(Oc2ccc(C=O)cc2)OC(COC(C)=O)C(OC(C)=O)C1OC(C)=O
b C/C(N)=C(/C#N)C(=O)CSc1nnc(SCc2ccc(Cl)cc2)s1
Answer: b. C/C(N)=C(/C#N)C(=O)CSc1nnc(SCc2ccc(Cl)cc2)s1
