At nodes pressure change (strain) is maximum and at antinodes it is minimum
 
hence option B is correct.
 
Hope it helps

Dear student
At nodes pressure change (strain) is maximum .A node is a position of zero displacement andmaximum strain whereas an antinode is the position of maximumdisplacement and zero strain, The amplitude of vibration gradually increases from zero at node tomaximum at antinode.
