your answer:

The reason why the bulb filament burns is that the heating effect produced by the current is more than what the filament can is built up for.

We know, the heat generated in a conductor is directly proportional to the magnitude of current passing through it.

A.) The method that he should use to connect the bulbs is a series connection.

We know that connecting electrical elements in series leads to a greater effective resistance, which means that less current is passed through each bulb.

B.) In series connection, the potential difference across each circuit element would be same while the current across each circuit element would be different (i.e. less than the total current).

The effective resistance of the circuit would be equal to the sum of their individual resistances.
