A is correct Router on a stick configuration

Other than router on a stick, how else could different vlans interact with each other?

A is correct. in a corporate Network, we don´t waste interfaces.

VLANs can't communicate with each othe

A is correct

A is correct because that is how Router on a Stick in implemented

A and B are correct however A - Router on a stick is the method. If the answer was B, you would have to have a switch port on the the router for each VLAN. Answer A - router on a stick creates sub interfaces for each VLAN eliminating the need for a switch port for each VLAN

A is correct. In other words, have a Router On A Stick (ROAS). Another option could be to have a Layer 3 Switch with SVIs (Switched Virtual Interfaces) and the appropriate IP addressing.

Yes A is the right answer. https://www.practicalnetworking.net/stand-alone/routing-between-vlans/#:~:text=There%20are%20three%20options%20available%20in%20order%20to%20enable%20routing%20between%20the%20VLANs https://www.ciscopress.com/articles/article.asp?p=2990405&seqNum=2#:~:text=The%20encapsulation%20command%2C%20and%20not%20the%20subinterface%20number%2C%20defines%20the%20VLAN%20ID%20associated%20with%20the%20subinterface https://www.firewall.cx/networking-topics/vlan-networks/218-vlan-access-trunk-links.html#:~:text=these%20two%20VLANs%20do%20not%20exchange%20any%20traffic%20between%20each%20other%2C%20unless%20we%20are%20using%20a%20layer%203%20switch%20(or%20router)%20and%20we%20have%20explicitly%20configured%20the%20switch%20to%20route%20traffic%20between%20the%20two%20VLANs

Yes oooMooo, but "subinterfaces" are not required. Like you said, essentially a connection to each VLAN, and IP for each connection.

A is correct. "For inter-VLAN communication, a layer 3 device (usually a router) is needed. This layer 3 device needs to have an IP address in each subnet (VLAN) and have a connected route to each of those subnets. The hosts in each subnet can use the router’s IP addresses as their default gateway."
