The game will be played at the Wankhede Stadium from Wednesday (November 28).
20-year-old Armaan, who has earlier played three First-Class matches for Mumbai in 2016, is the nephew of former India player and domestic stalwart Wasim Jaffer.
Earlier this month, Armaan slammed an unbeaten triple hundred for Mumbai in their U-23 Col C K Nayudu Trophy match against Saurashtra, finishing on 300 runs off 367-balls, inclusive of 26 boundaries and 10 sixes.
The Mumbai team will be led by pacer Dhawal Kulkarni and comprises regulars like Akhil Herwadkar, Siddesh Lad, Jay Bista and experienced wicket-keeper batsman Aditya Tare.
Medium-pacers Akash Parkar, Tushar Deshpande, spinner Karsh Kothari and all-rounder Shivam Dube have also been named in the 14-member squad.
A senior MCA official said Shreyas Iyer wasn't available for selection as he is part of the India A ODI squad that will play three games against New Zealand A in New Zealand.
Mumbai have played two Ranji games so far this season and both the games ended in draw. Thus, when the players take the field on Wednesday, they will aim for an outright win.
