Task: Answer the multiple-choice question.
Question: Which drug exhibits a -3.812\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: CN1CC2=Cc3ccccc3OC23Oc2ccccc2C=C3C1
b: CCOC(=O)c1cc(-c2ccccc2)nn1-c1ccccn1
c: C[C@H](NC(=O)[C@H](Cc1ccccc1)n1c(=O)[nH]c2ccccc2c1=O)C(=O)N1CCC(C(=O)O)CC1
Answer: a. CN1CC2=Cc3ccccc3OC23Oc2ccccc2C=C3C1
