Task: Answer the multiple choice question.
Query: Which drug has a 2.798\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) O=C(/C=C/c1cccc([N+](=O)[O-])c1)N(c1ccccn1)c1ccccn1
b) O=C(CCN1CCOCC1)Nc1c(-c2ccccc2)c2cc(Br)ccc2[nH]c1=O
Answer: a. O=C(/C=C/c1cccc([N+](=O)[O-])c1)N(c1ccccn1)c1ccccn1
