Task: Answer the multiple-choice question.
Question: Which drug exhibits a 0.483\% 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: Br.Clc1ccc(C2=CSC3=NCCN23)cc1Cl
b: C=CCn1sc(N)c(C(=O)OCC)c1=S
Answer: b. C=CCn1sc(N)c(C(=O)OCC)c1=S
