The correct answer is A. Most reactive non metals.
Firstly if some one knows how to read the periodic table he would have no confusion in deciding whether group 7 has metals or non metals. Group 7 contains non metals so basically we can easily cancel out two options of metals.
Secondly group 7 non metals are the most reactive non metals as they need only one electron in order to complete their valence shell and become stable.
Answer:
linear acceleration

angular acceleration

Explanation:
As we know that the force due to tension force is upwards while weight of the disc is downwards
so we will have

also we have

now we have


now we have


so we have
linear acceleration

angular acceleration
