Task: Answer the multiple choice question.
Question: Which drug exhibits a 3.495\% 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 additional words.
Options:
a: CC(C)(C)OC(=O)NCCNC(=O)c1cccs1
b: COc1ccccc1Nc1ncc(C(C)=O)c(C)n1
c: C=CCNc1ncnc2c1cnn2-c1ccc(Cl)cc1
d: C=CCn1c(Cc2csc(N)n2)nnc1SCC(=O)OCC
Answer: c. C=CCNc1ncnc2c1cnn2-c1ccc(Cl)cc1
