Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.487\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:

b) Cc1ccc(Oc2ccc(Cl)cc2NC(=O)c2cnccn2)cc1
c) COc1ccc(-n2nc(C(=O)NCC(=O)N3CCCCCC3)c3ccccc3c2=O)cc1Cl
d) O=C(Nc1ccccc1)OC1CC2CC1C1CCCC21
e) CCN1CCN(S(=O)(=O)c2ccc(Cl)c(C(=O)Nc3nnc(C)s3)c2)CC1
Answer: b. Cc1ccc(Oc2ccc(Cl)cc2NC(=O)c2cnccn2)cc1
