Task: Answer the multiple choice question.
Question: Which drug exhibits a 13.556\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a CN(C[C@H](Cc1ccccc1)N(C[C@H](Cc1ccccc1)N(CC1(c2ccccc2)CC1)N=O)N=O)N=O.[Na+]
b C=CCOC(=O)/C=C/C(=O)NC(N)=O
Answer: a. CN(C[C@H](Cc1ccccc1)N(C[C@H](Cc1ccccc1)N(CC1(c2ccccc2)CC1)N=O)N=O)N=O.[Na+]
