Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 16.031\% 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. C=C(C)c1cccc(C(C)(C)NC(=O)Nc2cc(C)ccc2OC)c1
b. CNC(=O)CN(c1cc(C)ccc1C)S(C)(=O)=O
c. CCCCOC(=O)c1ccccc1C(=O)OCCCC
d. CCCc1nn(CCc2ccccn2)c(N)c1CC
Answer: c. CCCCOC(=O)c1ccccc1C(=O)OCCCC
