Task: Answer the multiple choice question.
Question: Which compound exhibits a 16.124\% 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 other words.
Options:
a Cn1c(C(=O)O)cc2cc(F)ccc21
b CN(C)CCNC(=O)c1cccc(S(=O)(=O)Nc2ccc(F)cc2)c1.Cl
c O=C(COC(=O)c1ccco1)Nc1nnc(-c2ccccc2)o1
d COc1ccc(C(=O)c2c(N)sc3c2CCN(C)C3)cc1
Answer: c. O=C(COC(=O)c1ccco1)Nc1nnc(-c2ccccc2)o1
