  1 only
• B.
  2 only
• C.
  Both 1 and 2
• D.
  Neither 1 nor 2

Answer 1

The correct option is A

1 only
Explanation:

Statement 1 is incorrect: Waves are actually the energy, not the water as such, which moves across the ocean surface. The periodical rise and fall of the sea level, once or twice a day, mainly due to the attraction of the sun and the moon, is called a tide.

Statement 2 is correct: Centrifugal force is instrumental in formation of tidal bulges around the surface of the earth. This is a property which is attributed to the rotation of the earth around its axis. A resultant of this centrifugal force and the force of gravity exerted by the sun and the moon is what leads to formation of tides.
