Answer:

B

Step-by-step explanation:

As we know, The sum of four angles of a quadrilateral is 360 °

Let us check which sums up to 360°.

a) = 50°,70°,110°,70°.

The sum of these are 50°+70°+110°+70

Therefore, we get 300.

So a is not a Quadrilateral.

b) = 90°,120°,60°,90°

The sum of these are 90°+120°+60°+90°

Therefore, we get 360.

So b is a Quadrilateral.

c) = 20°,80°,90°,40°

The sum of these are 20°+80°+90°+40°

Therefore, we get 230.

So c is not a Quadrilateral.

d) = 90°,140°,60°,90°​

The sum of these are 90°,140°,60°,90°​

Therefore, we get 380.

So d is not a Quadrilateral.

The only Quadrilateral among a, b, c and d is b

Hope it helps you!!!
