Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.992\% 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 Cc1ccc(OCC(=O)Nc2oc(-c3ccccc3)c(-c3ccccc3)c2C#N)cc1
b COc1ccc(S(=O)(=O)N2CCCC2)cc1C(=O)N1CCOCC1
c CCOC(=O)Cn1nc(-c2ccccc2)nc1-c1ccccc1
d CCOC(=O)C1=NN(C(C)=O)C2(CC(=O)N(c3cccc(C)c3)C2=O)C1
Answer: c. CCOC(=O)Cn1nc(-c2ccccc2)nc1-c1ccccc1
