Problem statement: Answer the MCQ question.
Query: Which drug exhibits a 6.290\% 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(N2CCN(c3ncnc4c3cnn4-c3ccc(C)cc3C)CC2)cc1
b. C=CCSc1nc2c(c(=O)[nH]1)C(C(C)C)C(C#N)=C(N)O2
c. CCOC(=O)c1c(NC(=O)COC(=O)CCOc2ccc(OCC)cc2)sc(C(=O)N(C)C)c1C
Answer: b. C=CCSc1nc2c(c(=O)[nH]1)C(C(C)C)C(C#N)=C(N)O2
