The correct answer is (A) from 2nd to 3rd shell.
The explanation :
when a gain of energy is the shift of the electrons from a shell of low energy to the shell of high energy
and we have here 2nd shell is the shell of low energy, and 3rd shell is the shell of high energy.
∴ (A) from 2nd to 3rd shell is the correct answer.

Hi,
The answer is HF since hydrogen bonds are can be formed only between Hydrogen and Fluorine, Oxygen or Nitrogen.
For the first question it would be a unit obtained from the change in velocity per unit of time or m/s^2.
The vf and vi represent the final and initial velocity of the object and or item.
Knowing the formula for acceleration is simply change in velocity divided by time
Vi = 0
Vf = 27 m/s
t = 10 s
Vf = vi + at
27 = 10a
a = 27/10 or 2.7 m/s^2.
