All three cars in your options average around 8 to 12 kmpl depending on your driving styles and route.
For your money a good 2019/2020 1.5 Standard City AT driven under 30k should be an easy find in under 3.5 to 3.8 million easily.
If you want a bigger better car compromise 1 kmpl on fuel economy Corolla 1.6 hands down.
I bot a city aspire in 2022, when Corolla 1.6 was only 2.5 lack more pricier then City aspire.
Today Corolla 1.6 CVT is 12 lack 50 thousand more pricier then a City Aspire.
The most upper model car you can get is a City. Most durable, cheap to maintain you can get is a Corolla.
Maybe you can even find a new City 1.2 in your price range (2021/2022).
And if your only concern is fuel economy, get a Suzuki Cultus does upto 15 kmpl in City.
