Task: Answer the multiple choice question.
Query: Which drug exhibits a -1.434\% 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.) CCn1c(N)c(C(=O)NC)sc1=S
b.) O=C(NC1CC2CCCC(C1)N2Cc1cccs1)c1ccc([N+](=O)[O-])cc1
Answer: a. CCn1c(N)c(C(=O)NC)sc1=S
