Answer:
Option A, Cohesion is caused by polar water molecules attracting each other
Explanation:
Cohesion leads to attraction of molecules towards each other. Water molecules being polar in nature exhibit strong cohesive force.
Due to its polar nature, water molecule align itself in a way that its one end becomes positive with H+ ion and the other end becomes negative with OH- ion.
Two water molecules get attracted towards each other through the formation of hydrogen bond between them, due to which high cohesion arises.
Hence, option A is the correct answer.
