Answer #1

The answer to the question is given below.

The statement is true.

If we increase the Phase Modulation index. It results to increase in the modulated signal's bandwidth.

Relationship between the modulation index and bandwidth
BW = 2 (b + 1 ) fm

Here BW is bandwidth, and b is modulation index.
So, as we can see in the formula, if b is increased then BW will also increase.
