Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 12.672\% 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. O=C(COC(=O)c1ccccn1)Nc1c(Cl)cccc1Cl
b. CCOC(=O)CC1(c2ccccc2)CCOC(C)(C)C1
c. COC(=O)c1cc(C#N)c(N(C)Cc2ccccc2)nc1C
d. O=C(NC1CCCCC1NC(=O)c1cccs1)c1cccs1
Answer: c. COC(=O)c1cc(C#N)c(N(C)Cc2ccccc2)nc1C
