Task: Answer the MCQ question.
Query: Which compound exhibits a 6.905% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) O=C(Nc1cccc([N+](=O)[O-])c1)NC1CCCCCCC1
b) CCOC(=O)/C(C(N)=NCCCO)=C(\O)OCC
c) O=C1NC(Cc2c[nH]c3ccccc23)C(=O)N1c1ccc(F)cc1
d) O=C(O)C(Cc1c[nH]c2ccccc12)NS(=O)(=O)c1cccc(Cl)c1Cl
Answer: a. O=C(Nc1cccc([N+](=O)[O-])c1)NC1CCCCCCC1
