Probably a hair clog. Get a bucket and open the trap under the sink and clean it out. Chemical drain cleaner may also work but don't attempt to clean out the trap if you've used the chemical drain cleaner.
The most common reason for a sink line to plug is actually from soap build-up. Soaps are made from greases and fats and turn back into them when they sit in the line. They slowly make the pipe smaller and smaller until it plugs either from a chunk of food or any other debris going down. Potato peels, onions, pastas, and anything stringy like celery or banana peels can also plug the line.
Lavatory sinks, tubs and showers are usually plugged by a combination of soap build up and hair. Quite often lavatory sink back ups can be fixed by simply removing and cleaning the pop-up assembly.
All of the drain pipes in your house are connected to one pipe that either drains into the septic tank or the sewer system. It sounds like you have a clogged pipe somewhere down the line or a full septic tank. Try Drano or another liquid type drain cleaner. Follow the directions carefully as it is very caustic. If that does not work then you may have to call a plumber. If you have a drain snake you may be able to clear the clog yourself. Good luck.
Line to the sewer is blocked. Try filling the basement sink with hot soapy water and letting it go. That would clear grease out. Could have a root in your outside line.
If you have a basement floor drain, chances are that you have a clog downstream somewhere, and it's backing up into your basement.
I would have to say probably. I would get rid of the water in your basement just to make sure. If you do leave the water in the basement and it creates mold it may cost a fortune to fix
If you have your own water heater there should be a shut off at the heater. If not I would look under the kitchen sink. There may be shut off valves at each fixture. If there is a central water heater in the basement, there would be a shut off to each unit.

I have an LPG gas detector in my kitchen to detect any leaks from my appliances. Would I be able to install one in my basement? yes, detectors should be on every level
You can place any type of gas or electric water heater in a basement. I have seen many of both.

The musty smell of moisture and possible water marks would indicate that there is a problem with water.
This is baking soda and Sprite.
That would be your flush valve in the tank
