Question

How to setup navigation links in landing/homepage for Site Collection B/C/D with their respective SharePoint groups as target audience.

Answer 1

Audience targeting cannot be done using SharePoint groups in general, much less SharePoint groups in another site collection. Active Directory groups are available for audience targeting, so if available, use them.
