Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 0.408\% 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: COc1ccc(Cl)cc1-n1c(N)c(C(N)=O)sc1=S
b: COCCCN=C1NN=C(c2cc(C)n(-c3ccccc3F)c2C)CS1
c: CCOC(=O)c1c(NC(=O)Cc2cccs2)sc(C(=O)NC2CCCC2)c1C
d: O=S(=O)(NCCc1ccc(Cl)cc1)c1cccc2cccnc12
Answer: c. CCOC(=O)c1c(NC(=O)Cc2cccs2)sc(C(=O)NC2CCCC2)c1C
