Task: Answer the multiple choice question.
Question: Which drug has a 2.211\% 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 additional words.
Options:
a. CC(=O)Nc1ccc(OC(=O)c2cc([N+](=O)[O-])ccc2Cl)cc1
b. O=C(Nc1ccc(OC(F)(F)F)cc1)c1ccc(S(=O)(=O)N2CCOCC2)o1
c. CN1CCN(Cc2nc(Cc3ccccc3)no2)CC1c1ccccc1
d. CN(C)c1cccc(C(=O)N/N=C/c2ccsc2)c1
Answer: a. CC(=O)Nc1ccc(OC(=O)c2cc([N+](=O)[O-])ccc2Cl)cc1
