Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 3.510\% 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 or b without using any additional words.
Options:
a CC1(C)CN(c2ccc(C(=O)c3ccccc3)cc2)C1=O
b O=C(c1cc2ccccc2o1)N1CCN(c2ccccc2Cl)CC1
Answer: b. O=C(c1cc2ccccc2o1)N1CCN(c2ccccc2Cl)CC1
