Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.771\% 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, b, or c without using any additional words.
Options:
a: O=C(CCl)N1CCN(S(=O)(=O)c2ccc3c(c2)CCC3)CC1
b: CNC(=S)N1N=C(c2ccc(C)cc2)CC1c1ccc(OC)cc1
c: CC1CCN(c2ccccc2NC(=S)NC(=O)c2cccs2)CC1
Answer: a. O=C(CCl)N1CCN(S(=O)(=O)c2ccc3c(c2)CCC3)CC1
