Solution

The correct options are
B may increase or decrease
D may remains same
The liquid level depends upon the coefficients of expansion of the liquid and the vessel.
If $γ_{v e s s e l} > γ_{l i q u i d}$ , level decreases.
If $γ_{v e s s e l} < γ_{l i q u i d}$ , level increases.
If $γ_{v e s s e l = γ_{l i q u i d}}$ , level remains same.
