Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 3.449\% 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 additional words.
Options:
a. O=S(=O)(c1cnccc1N1CCN(/N=C/c2ccccc2)CC1)N1CCCCC1
b. O=C(Nc1ccc(Cl)cc1)N1CCN(c2ncccn2)CC1
Answer: b. O=C(Nc1ccc(Cl)cc1)N1CCN(c2ncccn2)CC1
