Hi...
Looking at the x-ray report your one of the cavities is deep but can’t really appreciate it well enough to decide if it needs an RCT as that would require a clear Xray of that particular tooth.
Also do you have any sensitivity or pain in that particular tooth that could also help in deciding if only a filling could help.
If you got this from outside India they have different line of thought on treatment of deep caries compared to that in India.
If possible get a clear x-ray of that particular tooth or go for a second opinion if you’re not satisfied.
Next Steps
Consult a dentist again online/offline with clearer x-ray if available
