Where to invest 50L for daughter's future?

Hey everyone,

My wife and I have saved around 50L and want to invest this amount for our daughter's (18 months old) future education. My wife wants to park this money in some property, but given the inflated property prices, no plots in this range are available in good areas, and our only real estate options in this budget are high-rise flats, which we want to avoid.

So please recommend a diversified investment plan for this amount. The investment period will be around 17-18 years.

Thank you.
