It is great to know that you have a 15-20 year investment horizon. Considering your long-term investment horizon and the benefits of compounding, you could consider the use of a combination of an index ETF, a multicap fund and a midcap fund. The Reliance Nifty ETF- Growth, Kotak Select Focus Fund - Growth, and the Franklin India Prima Fund - Growth could be good options to consider. Rebalance towards safer investments gradually a few years before you need the funds.
