Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.490\% 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=C1CC(c2ccc(S(=O)(=O)Nc3cc(C(F)(F)F)cc(C(F)(F)F)c3)cc2)CN1
(b) Cc1cccc(NC(=O)CN2CCN(C(=O)C3CCCO3)CC2)c1C
Answer: a. O=C1CC(c2ccc(S(=O)(=O)Nc3cc(C(F)(F)F)cc(C(F)(F)F)c3)cc2)CN1
