Online off-Market transfer to relative - Found 2 options - "Gift" & "Trnfr btwn specified Family Members"

Hi…
I like to transfer some holdings to my brother’s daughter Demat account from my NSDL ( Stock Holding Corporation of India Ltd.,) demat account.
Found two similar options under reason for transfer - Gift and Transfer between specified family members (self and spouse linear ascendants/descendants ).
Can anyone please enlighten about income tax implication on "Gifting" and “Transfer between specified family members”
Regards,
