Problem statement: Answer the multiple choice question.
Question: Which drug has a 6.285\% 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(O)Cn1nnc(-c2cccs2)n1
[b] O=C(CN1CCN(Cc2ccccc2)CC1)N/N=C/c1cccnc1
Answer: a. O=C(O)Cn1nnc(-c2cccs2)n1
