Task: Answer the multiple choice question.
Question: Which drug has a -1.201\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a O=C(Cc1ccccc1)NNc1ccc2ccccc2c1
b O=c1c(OC2OC(CO)C(O)C(O)C2OC2OC(CO)C(O)C(O)C2O)c(-c2ccc(O)cc2)oc2cc(O)cc(O)c12
c O=C(CN1CCN(c2ccc(Cl)cc2[N+](=O)[O-])CC1)N1CCOCC1
d Cc1cc(C(=O)Nn2c(C)nc3ccccc3c2=O)ccc1[N+](=O)[O-]
e COc1ccc(/C=N/OC(=O)Nc2ccccc2)cc1[N+](=O)[O-]
Answer: a. O=C(Cc1ccccc1)NNc1ccc2ccccc2c1
