Explanation:

The fragment A of the sentence is erroneous. The expression 'lag ahead' is absurd.

The correct phrasal verb is 'lag behind' which means ‘to move at a slower pace than someone or something’

The correct sentence would be:

While the tooth fairy continues to lag behind tech developments, there are already piggy bank apps, ones for pocket money with contactless cards, and schools use cashless payment systems for lunches and trips

Hence, option A the correct answer.
