We know that the difference of any two sides of a triangle is less than the third side.
So, (AB – AC) must be less than 3 cm.
Options (A), (B) and (C) do not satisfy the above condition.
When AB – AC = 2.8 cm, the condition satisfies.
Ans. The construction of the given ΔABC is possible when difference of AB and AC is equal to 2.8 cm.
