Which of these investment options will you choose - Blue Chip vs Roboadvisors vs US ETFs?

I have a small sum of money that I can use for investment (around 3k). Here are the options I’ve considered. Out of these options, which do you think is the best?
1) 100% into DBS stock: This is because if I were to buy an individual stock, with the minimum commission it would be best for me to invest a large sum at one go. I’m looking at DBS for high dividend yield
2) 40% into Stashaway, 60% into Syfe REITS
3) 60% into IWDA, 40% into Syfe REITS
4) 60% into IWDA, 40% into QQQ
