Resistance of bulb P=
R
V

In parallel connection, same potential difference develops through all the bulbs.
So, brightness is inversely proportional to resistance and thus is directly proportional to power of bulb.
Thus, bulb having the most power and least resistance will glow with maximum brightness.
