Problem statement: Answer the multiple choice question.
Query: Which drug has a -30.916\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. Nc1nc(-c2ccccc2)c(-c2ccc([N+](=O)[O-])cc2)s1
b. COc1cc2c(cc1OC)C(SC)=NC1(CCCC1)C2
c. CCOC(=O)C(CC)Sc1nc2c(c(=O)[nH]c(=O)n2C)n1CCc1ccccc1
Answer: c. CCOC(=O)C(CC)Sc1nc2c(c(=O)[nH]c(=O)n2C)n1CCc1ccccc1
