Is XBRL filing is mandatory of AOC-4 if once applicable even when we slipped down the limit or we can file normally?

I have a query in Section 186. I am not clear with the language of the law. What does the law want to convey by using this language - "A company to make Investment through not more than two layers of Investment companies" This line is not clear to me, How can one make Investment in Companies through Investment companies?

Sir/Mam, I wanna know that after being CA is it compulsory for anyone to practice in India only or we can also practice in other countries or we have to pursue another course after being CA to practice in another country?

Respected Experts,
Kindly let me know that in CS Professional which subject is good for future prospects, Insurance Law & Practice or International Business Law & Practice ?
As i gave two attempts with insurance Law but got very low marks & i also saw that ICSI is giving very low marks in Insurance Law .
Should i change the elective subject ? If yes , International Business Law & Practice will be good to score more?
Please provide your valuable guidance to me.
Thanking You
