Step 1: List what each statement adds.
The family has seven members: Ritu, Deep, Lakshya, Krish, Suja, Adi and Anu.
We must find exactly how Suja relates to Adi.
Step 2: Check statement 1 alone.
Statement 1 says Ritu has a grandson and a granddaughter, and that Anu is Krish's niece.
This fixes Krish as an uncle of Anu, but it never mentions Suja or Adi together.
No link between Suja and Adi can be built from this statement alone.
Statement 1 alone is not sufficient.
Step 3: Check statement 2 alone.
Statement 2 says Suja is Lakshya's sister-in-law, and that Deep is the father of Adi and Anu.
A sister-in-law can be a spouse's sister or a sibling's spouse, so this alone does not confirm whether Suja is related to Deep's side or Lakshya's side.
Without knowing if Lakshya is Deep's wife or Deep's sister, Suja's link to Adi stays unclear.
Statement 2 alone is not sufficient.
Step 4: Combine both statements.
Even together, the statements never state whether Lakshya is married to Deep or is Deep's sister.
Both readings of sister-in-law remain possible, so Suja's exact relation to Adi, aunt by marriage or by blood, cannot be pinned down.
The combined data still leaves more than one valid family tree.
Final Answer:
Neither statement, alone or combined, fixes the relationship between Suja and Adi. \[ \boxed{\text{Neither statement suffices (option e)}} \]
