Task: Answer the multiple-choice question.
Question: Which drug exhibits a -2.400\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a. C=CCn1c(O)c2ccc(C(=O)N=NC(=O)c3ccc(F)cc3)cc2c1O
b. CCCN1CCN(C(=O)CN(c2ccc(C(C)C)cc2)S(=O)(=O)c2c(C)nn(C)c2C)CC1
c. O=c1c2ccccc2ncn1C1CCCCC1
d. COc1ccc(C(CC(=O)Nc2ncccc2C)N2Cc3ccccc3C2=O)cc1OC
e. C/C(=C\c1ccccc1F)C1Nc2cccc3cccc(c23)N1
Answer: c. O=c1c2ccccc2ncn1C1CCCCC1
