Problem statement: Answer the multiple choice question.
Query: Which compound has a 14.308\% 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 O=C(Nc1ccc(C(=O)O)cc1)/C(=C\c1cccc([N+](=O)[O-])c1)NC(=O)c1ccc(Br)o1
b Cc1ccc(CNS(=O)(=O)c2ccc3c(c2)C(C)(C)C(=O)N3C)cc1
c O=C(c1ccccc1)N(C1=NCCCCS1)c1ccccc1
d CCN(CC)CCN1C(=O)/C(=C\c2ccc(Cl)c([N+](=O)[O-])c2)SC1=Nc1ccc(OC)cc1
Answer: a. O=C(Nc1ccc(C(=O)O)cc1)/C(=C\c1cccc([N+](=O)[O-])c1)NC(=O)c1ccc(Br)o1
