Task: Answer the multiple-choice question.
Query: Which drug exhibits a 24.312\% 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 additional words.
Options:
a. O=C(N/N=C/c1ccccn1)c1ccc([N+](=O)[O-])cc1
b. CCCCc1c(C(=O)O)cc(OC)cc1C(=O)O
c. CC(=O)c1nc2ccccc2n1S(=O)(=O)c1ccc(Cl)cc1
d. CCOC(=O)/C(C#N)=C\c1ccc(OC)c(OC)c1
e. CCc1nn(CC(=O)NCCc2ccc(Cl)cc2)c(=O)c2cccn12
Answer: a. O=C(N/N=C/c1ccccn1)c1ccc([N+](=O)[O-])cc1
