Answer 2

Answer:

Let, side a= 5cm.

side b= 1.5cm.

c=?

now, 5+ 1.5= 3.5

We know that, a closed figure formed by three intersecting lines (or sides) is called a triangle, if difference of two sides < third side and sum of two sides > third side

∴ 5-1.5 < BC and 5+1.5 > BC

⇒ 3.5 < BC and 6.5 > BC

Here, we see that options (a), (b) and (c) satisfy the above inequality but option (d) does not satisfy the above inequality.
