Eliminating One Bathroom Sink

I'm remodeling a bathroom and eliminating one of two vanity sinks in the process.

The left side sink is the one being eliminated. There is a roughly 7' drain run (iron) through the wall where it connects to the right side sink drain, which is right above/near the main soil pipe.

What is the best method to abandon the drain line inside the wall? Can I just cap it at the current location (along with the supply lines) and drywall over? That would be a good option in case anyone wanted to install a second sink again in the future.

Does that leave too much potential for a leak, backup, damage, .... I have full access to the plumbing from the basement, so I can also cap the supply lines down there.

Cap the waste in the wall and the water as close to the mains as possible

DRAIN--Unscrew the nipple that is sticking out of the wall ---screw in a plug (doped and taped)

Water lines---those are old pipes--safest to remove and cap in the crawlspace--
