@narasimham Hi, make sure you have been enabled to use Forms Pro, if this is working it will say Forms Pro in the top left side of the screen beside the Office apps menu. The screenshot you posted indicates it's just using the regular Microsoft Forms, which doesn't come with the Send option.
Customers with certain Dynamics 365 licenses have Forms Pro included, in other cases, it may have to be purchased separately as an add-on. If you have a Dynamics 365 license that comes with Forms Pro, you may have to use the Switch to Forms Pro option from clicking your username from the upper-right corner of the page though to enable it, otherwise, it's worth checking with your IT people to make sure it's been enabled.
There is more information here including information for administrators - Purchase Microsoft Forms Pro.
