Question

circle the option number of incorrect pair .area- square metre, time - second, mass- litre

Answer 1

HI
HERE IS THE ANSWER

OPTION 3 MASS-LITRE IS INCORRECT.

Answer 2

$\boxed{ANSWER...!!}$

Area = square metre..

After finding area of any figure we give it's S.I unit as $m^2 \: or\: cm^2$.
So, this pair is correct.

Time = Second..

The S.I unit of time is second , so this pair is correct.

Mass = Litre..

The S.I unit of mass is Kg , and here it is given litre , so it is incorrect.

.

So , out of the three pair , the third pair (Mass = litre) is incorrect.
