Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.856\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CN1CCN(c2ccc(NC(=O)Oc3ccccc3)cc2)CC1
b: CCc1ccc(N2CC(C(=O)Nc3nc4ccc(S(C)(=O)=O)cc4s3)CC2=O)cc1
c: CCCC[C@@H]1C[C@H]1[C@@H](NC(=O)c1ccccc1)c1ccccc1C(F)(F)F
d: COc1ccc(N(C(=O)c2cccnc2)S(=O)(=O)c2cccs2)cc1
Answer: b. CCc1ccc(N2CC(C(=O)Nc3nc4ccc(S(C)(=O)=O)cc4s3)CC2=O)cc1
