Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.711\% 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(NCCCn1ccnc1)Nc1cccc2ccccc12
(b) O=C(NC1CC1)c1c[nH]c2ccc(S(=O)(=O)Nc3cccc(C(F)(F)F)c3)cc2c1=O
Answer: a. O=C(NCCCn1ccnc1)Nc1cccc2ccccc12
