Task: Answer the multiple choice question.
Question: Which drug has a -4.987\% 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 additional words.
Options:
[a] CC(C)(CO)Nc1ccc([N+](=O)[O-])cc1[N+](=O)[O-]
[b] O=C(C1Cc2ccccc2CN1S(=O)(=O)c1cccs1)N1CCCCCC1
[c] O=S(=O)(c1ccc(Cl)cc1)N1CCNCC1
[d] Nc1ccc(N2CCOCC2)c(S(=O)(=O)Nc2cc(Cl)ccc2Cl)c1
Answer: a. CC(C)(CO)Nc1ccc([N+](=O)[O-])cc1[N+](=O)[O-]
