Task: Answer the multiple choice question.
Query: Which drug has a 12.600\% 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. O=C(Nc1ccccc1)Nc1nncs1
b. COC(=O)C1=C(C)N(C2CCCC2)C(=O)C1(NC(C)=O)C(F)(F)F
c. COCCN(C(=O)CSc1nc2ccccc2c(=O)n1CCOC)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
d. Cc1c(Cl)cccc1N/C(=N/S(=O)(=O)c1cccs1)c1ccccc1
Answer: c. COCCN(C(=O)CSc1nc2ccccc2c(=O)n1CCOC)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
