Fake dowry and dv case

Hi Sir, I was married in June 2019 and in 2020 Aug I and my wife blessed with a baby boy. Soon after within 10 days my wife went to her parents place in early Sep 2020 and has not returned since then. She does not tell why she is not coming back nor her parents are sending her to my place. Its been almost a year since she is still there and now she has suddenly out of nowhere filed a police complaint citing demand of dowry during these two years by me and my family members, plus domestic violence against her whenever a luxury car was demanded from our side and one more significant charge - tried to poison her and the baby in the womb by me and my family members (JUST A DAY BEFORE DELIVERY) and we would declare the death due to corona in her 9th month of pregnancy. I and my family members have never demanded dowry nor ever assaulted her physically nor tried to kill her (and the baby in the womb). However the baby was born via operation and was healthy and also various imp tests were done and the doc would have raised concerns right then. I want to ask: 1) That mere making allegations is enough? She needs to prove also all such things. 2) if she was physically assaulted during that time why is she filing case after one year? 3) what if she fails to prove all the allegations? will she be punished? if yes then what case should i file against her and what should be punishment for her? Jailed or fine? 4) MOST IMPORTANTLY - now that she has filed a case with police (while she is living at her parents place) can she come back and demand to live or first the complaint needs to taken back by her only then she would be entitled to continue live here with me. THANK YOU SIRS AND MADAMS
