Task: Answer the multiple choice question.
Question: Which compound exhibits a 2.627\% human ether-à-go-go related gene (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(Nc1ccc(F)cc1)c1ccc(-n2cncn2)c([N+](=O)[O-])c1
b. COc1ccc(/C=C(/NC(=O)/C=C/c2ccccc2)C(=O)O)cc1
c. COc1cc(Br)cc(CN2CCN(C/C=C/c3ccccc3)CC2)c1O
d. Cc1ccc(S(=O)(=O)NC(=NC2CCCCC2)c2ccc(F)cc2)cc1
e. Cc1ccc(S(=O)(=O)c2nc(N3CCOCC3)sc2Cl)cc1
Answer: a. O=C(Nc1ccc(F)cc1)c1ccc(-n2cncn2)c([N+](=O)[O-])c1
