Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 8.315\% 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 CN(C)c1ccc(/C=N\NC(=O)c2csnn2)cc1
b COc1cccc(NC(=O)Cn2nnc(C(=O)NCc3ccc4c(c3)OCO4)c2N)c1
c O=C(Cn1cnc2ccccc2c1=O)c1cccs1
Answer: c. O=C(Cn1cnc2ccccc2c1=O)c1cccs1
