Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.441\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) CCn1c(NCc2cc(Cl)ccc2O)nc2ccccc21
(b) O=C(Cc1c(Cl)cccc1Cl)Nc1cccc(S(=O)(=O)N2CCOCC2)c1
(c) CC(C)NC(=O)COC(=O)Cn1[nH]c(=O)c2ccccc2c1=O
(d) CC(C)NC(=S)NN=C1CCC(c2ccccc2)CC1
Answer: c. CC(C)NC(=O)COC(=O)Cn1[nH]c(=O)c2ccccc2c1=O
