What was the meaning of 'camp towns' according to Bernier?

The correct answer is Option 2 - Towns that owed their existence, and depended for their survival, on the imperial camp.

Bernier described Mughal cities as “camp towns”, by which he meant towns that owed their existence, and depended for their survival, on the imperial camp. He believed that these came into existence when the imperial court moved in and rapidly declined when it moved out. He suggested that they did not have viable social and economic foundations but were dependent on imperial patronage.
