Need to add options in meraki but like option 3 should have two entries but meraki not accepting two entries for same option. Also need to enter option 1 but after saving meraki is saying doesn't support.
Well the way I see it you need to put in option 43 with all of its sub options in the payload (Meraki doesn't have the front-end to specify sub-options so you'll have to manually construct the whole payload).
I haven't done this myself. But out of interest I'm willing to help you construct your option 43 payload. I would need the actual values of all your suboptions to do that though. And seeing as I have no way to really test it, you'd have to be my guinnea pig.
Options in DHCP are defined in RFC 2132, 3046 and 3495. From the screenshot you took of your Microsoft DHCP, it appears the configuration you are trying to copy is non-standard. You need to adhere to the RFC's and not assign your DHCP options according to your preference. Vendor specific options start at 43.
iana.org has a good guide as to the expected option configuration per normal standards.
