The question is not about overall country but specific to peninsular India.
In intro, mention that peninsular India is one of the largest Precambrian shield which are considered to be stable but we have seen various earthquakes such as Bhuj, Latur, Koyna etc
After that mention some reasons for this-
Stresses resulting from collision of plates in India and North Asia, flexural bulge in Central India resulting from collision with Tibetan plateau
Presence of rifts/deep faults- Narmada, Tapti rift, Kurudwadi rift
Hydro-seismicity both reservoir induced and due to heavy rainfall can be elaborated a bit.
Examples mentioned are good.
Diagram is also fine, if you can shoe the major fault lines, it will be better.
Conclusion is fine.
Read a bit more about the topic.
Keep practicing. 🙂

Introduction, way forward and conclusion are good.
Reasons can be a bit more elaborate.
That is the main demand of the question.
Mention should be made of-
Stresses resulting from collision of plates in India and North Asia, flexural bulge in Central India resulting from collision with Tibetan plateau
Presence of rifts/deep faults- Narmada, Tapti rift, Kurudwadi rift
Hydro-seismicity both reservoir induced and due to heavy rainfall can be elaborated a bit (percolation of water, fluid in fractures etc).
It will be nice if you can draw a diagram showing the deep fault lines and earthquakes due to them.

Introduction is fine and examples mentioned in the answer are good. However, Himalayan region is not asked. You have just shown overall earthquake zones.
However, question is about REASONS for seismicity in ‘peninsular India’. Being one of the oldest Precambrian shields, it should be stable but that is not the case.
Reasons could be-
Stresses resulting from collision of plates in India and North Asia, flexural bulge in Central India resulting from collision with Tibetan plateau
Presence of rifts/deep faults- Narmada, Tapti rift, Kurudwadi rift
Hydro-seismicity both reservoir induced and due to heavy rainfall can be elaborated a bit (percolation of water, fluid in fractures etc).
It will be nice if you can draw a diagram showing the deep fault lines and earthquakes due to them.
Read a bit more about the topic.
Conclusion and way forward part is fine.
Keep practicing. 🙂
