Here follows the explanation with proper reasons.

#### Explanation:

Phosphorus $\left(P\right)$ is having the highest atomic radii among all others. So $P - H$ bond is having the lowest polarity.

Now among, $C , N , O , F$, carbon is having highest electropositivity & moreover C has the highest atomic radii. So, C is having the lowest polarity among these four.

Now among, $N , O , F$, N has the highest electro positivity. So, N has the lowest polarity among these three.

Now among, $O , F$, O has the highest electro positivity. So, O has lower polarity than F.

Hence, the remaining F atom is having highest electonegativity among P,V,N,O and F.

So, the order of bond polarity in the order of increasing electro negativity is:

$P - H < C - H < N - H < O - H < F - H$ .
