Task: Answer the multiple choice question.
Query: Which drug has a 7.775\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] O=C(Nc1cccc(NC(=O)c2ccccc2[N+](=O)[O-])n1)c1ccccc1[N+](=O)[O-]
[b] Cc1c(NC(=O)CN2C(=O)NC3(CCCC3)C2=O)c(=O)n(-c2ccccc2)n1C
[c] Cc1c(C(=O)NCCCN2CCCC2=O)oc2ccc(S(=O)(=O)N3CCOCC3)cc12
Answer: a. O=C(Nc1cccc(NC(=O)c2ccccc2[N+](=O)[O-])n1)c1ccccc1[N+](=O)[O-]
