Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.134\% 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 other words.
Options:
a. Cc1cc(C2=NNC(=NC3CC3)SC2)c(C)n1-c1c(C)n(C)n(-c2ccccc2)c1=O.Cl
b. Clc1ccc(OCCCCCN2CCOCC2)cc1
Answer: a. Cc1cc(C2=NNC(=NC3CC3)SC2)c(C)n1-c1c(C)n(C)n(-c2ccccc2)c1=O.Cl
