Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.464\% 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 O=C(c1cnn2c(C(F)(F)F)cc(-c3ccc4c(c3)OCO4)nc12)N1CCCC1
b N#Cc1c(N)sc(=S)c2c1CCCCC2
Answer: a. O=C(c1cnn2c(C(F)(F)F)cc(-c3ccc4c(c3)OCO4)nc12)N1CCCC1
