If I design presentation for client using assets of Adobe stock, if the client will print presentation , must use extended licence for these assets of Adobe stock?
Per the terms and conditions, clause 3.1 B (1)
If the client plans to print less than 500,000 copies a standard license will suffice.
I am not an attorney, nor am I an Adobe employee, and this is my opinion of the above- mentioned clause.
I would assume, that you can design your presentation with a standard licence. The only constraint I see is for a print run of 500k or more. I've never seen a presentation with such an interest.

(Disclaimer: As always with licensing, this is my interpretation of the rules. I think they are correct and advice is based on reading and interpreting the licence terms and on fair use for both the buyer and the artist/stock company, but I cannot rule out that my interpretation is wrong. I'm not an Adobe employee).
