Answer 1

Answer:

Option 4 :17 minutes

Explanation:

See every one minute it divides once.

so if in 15 mins it fills the cup to be one- fourth,

it'll double in a minute and fill half the cup in the next ie 16th minute and fill half the cup.

It'll fill the entire cup in the next minute ie the 17th minute.

Hope you understood :)
