Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.738\% 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:
a COc1ccccc1NC(=O)c1cnc2c(-c3ccccc3)c(C)nn2c1C
b CCOc1ccccc1N1CCN(C(=O)NCc2ccc(F)cc2)CC1
c O=C(CNC(=O)c1cccc(Cl)c1)NCCCSc1ccccc1
d CC(=O)Nc1ccc(S(=O)(=O)NCc2cccnc2)cc1
e O=C(NCCc1ccccn1)C1CCN(S(=O)(=O)c2ccc(Cl)cc2)CC1
Answer: b. CCOc1ccccc1N1CCN(C(=O)NCc2ccc(F)cc2)CC1
