Task: Answer the multiple choice question.
Query: Which drug has a 6.540\% 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.) Cc1ccc(C2C=C(c3ccccc3OC(F)F)Nc3ncnn32)cc1
b.) CCOc1ccc(C(=O)C(c2ccccc2)N2CCOCC2)cc1.Cl
c.) COc1ccccc1CC(NC(C)=O)C(=O)NC1CCN(C(=O)Nc2ccccc2C)CC1
d.) OCCN=Cc1c(O)[nH]c2ccccc12
Answer: a. Cc1ccc(C2C=C(c3ccccc3OC(F)F)Nc3ncnn32)cc1
