Task: Answer the multiple-choice question.
Query: Which compound has a 12.821\% human ether-à-go-go related gene (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: CCOC(=O)c1nnn(-c2nonc2N)c1-c1cccc2ccccc12
b: Cc1csc(NC(=O)c2c(-c3ccccc3)noc2C)n1
c: COc1c(Cl)cnn(-c2ccc(Cl)c(Cl)c2)c1=O
d: CCOC(=O)c1nnc(-c2ccccc2)[nH]c1=O
Answer: c. COc1c(Cl)cnn(-c2ccc(Cl)c(Cl)c2)c1=O
