Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 17.742\% 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, d, or e without using any other words.
Options:
a CCN(CC)c1ccc(C(=O)NNC(=O)CN2C(=O)NC(C)(c3ccccc3)C2=O)cc1
b CCCn1c(SCC(=O)N2CCCC(C)C2)nnc1-c1cccnc1
c CCOC(=O)N1c2ccccc2C=CC1OCC
d COc1ccc(S(=O)(=O)NCC(=O)Nc2ccc3c(c2)OCCO3)cc1OC
e COc1ccc(NC(=O)c2sc3nc(Cc4ccccc4)cc(C(F)(F)F)c3c2N)cc1OC
Answer: c. CCOC(=O)N1c2ccccc2C=CC1OCC
