bitcoin core – How can i do know which utxo in my pockets will likely be despatched?

Assuming that i’ve a number of utxos in my pockets.
Can i do know which utxos will likely be despatched when i request a transaction?
For instance, there are 3 utxos in my pockets: 3 BTC, 5 BTC, 7 BTC.
when i ship 1 BTC to somebody, which utxo will likely be spent?

1. greatest one first
2. oldest one first
3. smallest one first (however greater than sending quantity)

In fact it relies on the consumer program, however I am inquisitive about the way it runs on the whole.
(What about bitcoin-core or exchanges?)
