Task: Answer the multiple choice question.
Question: Which drug exhibits a -12.036\% 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=C(CCCCCNc1nc(=S)[nH]c2ccccc12)N1CCN(c2ccccn2)CC1
b: CCC(C)c1ccc(OCc2ccc(C(=O)OC)o2)cc1
Answer: a. O=C(CCCCCNc1nc(=S)[nH]c2ccccc12)N1CCN(c2ccccn2)CC1
