Answer 1

The Answer To This Is A , The Most Reactive Of The Alkali Explode Due To Reactions To Water

Answer 2

Alkali metals are all highly reactive (D is false) so they would not be found in their uncombined form (A is true) ans at least some of them are highly water soluble ( C is false) (b is false) Check out the Periodic Table - you will see the Alkali metals.
