Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.675\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a Cc1nn(CC(=O)NCCc2ccc(Cl)cc2)c(C)c1[N+](=O)[O-]
b O=C(Nc1cccc(F)c1)NC1CCCCC1
c CC(C)CC(CO)N1CCN(C(=O)c2ccc(Cl)c(Cl)c2)CCC1=O
Answer: b. O=C(Nc1cccc(F)c1)NC1CCCCC1
