Strontium is a metal and has a tendency to react with oxygen to form an oxide with the formula SrO. When this oxide dissolves in water, it forms a basic solution due to the presence of hydroxide ions (OH-) formed through the reaction of SrO with water. Therefore, the given observations match with the properties of strontium, and hence, the correct answer is A) strontium.
