As we discussed in concept

Non Inertial Frame of Reference -

Accelerated frames are Non Inertial.

Examples- car moving with uniform circular motion, plane which is taking off.

- wherein

Newton's law are not valid 

\vec a\neq0,      if \vec{F}= 0

\ast pseudo \left ( -m\vec{a} \right ) act on the body.

- means direction opposite  

 

 The surface of oil rise in backward direction because frame will behave as non inertial.

Remain unaffected

This option is incorrect.

Option 2)

Rise in forward direction

This option is incorrect.

Option 3)

Rise in backward direction

This option is correct.
