Problem statement: Answer the multiple choice question.
Query: Which compound has a 3.191\% 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 other words.
Options:
a O=C(Cn1cc2c(n1)CCCCC2)NCc1cccs1
b O=C(O)CC1S/C(=N\N=C2CCCCCC2)N(c2ccccc2)C1=O
Answer: b. O=C(O)CC1S/C(=N\N=C2CCCCCC2)N(c2ccccc2)C1=O
