Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 5.973\% 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) C=CCn1c(C(C)NC(=O)CCC)nc2ccccc21
b) O=c1cc(CN2CCN(Cc3ccccc3)CC2)c2cc3c(cc2o1)CCC3
Answer: a. C=CCn1c(C(C)NC(=O)CCC)nc2ccccc21
