Answer 2

Answer:

hey mate here is your answer ❤️❤️❤️

option c is the right answer..

Here we need to exactly measure these lengths.

Also, lm = 100 cm; ... 1m 35cm = 135cm and 1m 20cm = 120cm

Option 1- 5 cm can measure 30cm, 90cm, 1m 20cm and 1m 35 cm

Option 2 - 10 cm cannot measure 1m 35cm i.e. 135cm

Option 3 -15 cm can measure30cm, 90cm, 1m 20cm and 1m 35 cm

Option 4 -30 cm cannot measure 1m 35cm

Since we want greatest length 15 > 5

∴ Answer = 15cm
