Task: Answer the multiple-choice question.
Query: Which drug exhibits a 7.978\% 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 O=C(Cn1ccc([N+](=O)[O-])n1)N1CCc2ccccc21
b COc1cc(-c2nc(C(=O)NCC3CCCO3)cc3c2[nH]c2ccccc23)cc(OC)c1OC
c O=C(OCc1nc2ccsc2c(=O)[nH]1)c1ccccc1
d COc1cccc(C2C(C(=O)Nc3nc4ccccc4s3)=C(C)NC3=C2C(=O)CC(C)(C)C3)c1OC
Answer: a. O=C(Cn1ccc([N+](=O)[O-])n1)N1CCc2ccccc21
