Task: Answer the multiple choice question.
Question: Which compound exhibits a 7.557\% 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, or c without using any other words.
Options:
a CC(C)c1cc(=O)n2[nH]c(N)nc2n1
b O=S(=O)(NC1CCCCC1)c1ccc(Cl)nc1
c COCCOC(=O)C1=C(C)N=c2s/c(=C\c3cccs3)c(=O)n2C1c1cccs1
Answer: b. O=S(=O)(NC1CCCCC1)c1ccc(Cl)nc1
