I-797A or I-797B for H1B visa stamping ?

[amitdey]

Hi,

My current L1B expires on 2/2/2018.
My H1B Petition was approved this year.
My Visa Consulate Appointment for H1B stamping is on 11/30/2017.

But I seem to have two set of documents from USCIS.
Each set has a different WAC Receipt number.
I am not sure which one I should carry with me to the interview.

Set 1
Document Type - I-797B
Received on - 4/11/2017
Validity - 10/1/2017 to 2/1/2019

Set 2
Document Type - I-797A
Received On - 8/8/2017
Validity - 2/2/2018 to 2/1/2019
An I94 is attached.

Can you tell me which Set among above should be entered in my DS-160 and carried with me to interview ?
