Your intent of ending the case immediately actually depends on your Daughter-in-Law. As all the aforesaid Sections mentioned by you comes under the purview of a criminal act and unless and untill the complainant is proved wrong by the Hon'ble Court, the case cannot be settled in your favour.
Hence, it will all depend upon how the facts, circumstances and the case is represented in the MM Court on your behalf. How actually the case agasint you proceeds, will all depend upon the details of the complaint and the truth and the evidences behind it.
If the complainant (your daughter-in-law) is unable to prove the accusations & charges, you can very easily get a relief from the Hon'ble Court.
Even the Hon'ble Court, NOW, has a liberal approach towards these kinds of complaints as these are allegedly being used to misuse the law.
In my opinion, for a fast & concrete relief & resolution towards this issue, a detailed analysis of your side of the story and the details of the complaint, filed by your daughter-in-law is required. Do ensure to hire a good and competent Advocate to present a strong side of yours.
Best of Luck.
Thanks & Regards
