Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 6.875\% 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: CC1CCN(c2c(NCc3ccc(C(=O)NCc4ccco4)cc3)c(=O)c2=O)CC1
b: N/C(=N\OC(=O)c1cc(-c2ccccc2)nc2ccccc12)c1ccccn1
c: O=C(NCCOc1cccc(Oc2ccccc2)c1)c1cc(-n2cnnc2)ccc1Cl
d: CN(CC(=O)Nc1ccc(C#N)cc1)Cc1ccc(Cl)cc1
Answer: a. CC1CCN(c2c(NCc3ccc(C(=O)NCc4ccco4)cc3)c(=O)c2=O)CC1
