Task: Answer the multiple choice question.
Query: Which compound exhibits a 1.984\% hERG inhibition at a concentration of 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=[N+]([O-])c1ccc2nc(SCc3ccccc3Cl)sc2c1
b.) O=C(Cn1c(=O)oc2cc(S(=O)(=O)NCc3ccccc3)ccc21)NCc1ccco1
c.) COc1ccc(-c2nn3c(C4CCCCC4)nnc3s2)cc1OC
d.) O=C1c2cnc3nc(SCc4ccccc4)nn3c2CC2c3ccccc3CCN12
e.) O=C(/C=C/c1ccc([N+](=O)[O-])cc1)NCCc1ccccc1
Answer: a. O=[N+]([O-])c1ccc2nc(SCc3ccccc3Cl)sc2c1
