Task: Answer the multiple choice question.
Query: Which drug exhibits a 6.026\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. Cc1ccccc1NC(=O)c1cccc(N2C(=O)C3CCCCC3C2=O)c1
b. COc1ccccc1NS(=O)(=O)c1cc(C(=O)NCC(C)(C)N2CCOCC2)ccc1C
c. CCCCn1c(O)c(C(C)=Nc2ccc(OCC)cc2)c(=O)[nH]c1=O
Answer: c. CCCCn1c(O)c(C(C)=Nc2ccc(OCC)cc2)c(=O)[nH]c1=O
