Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. it is often called the universal solvent because it dissolves more substances than any other liquid. the reason for this is best explain by which of these? a) water is polar with a positive and negative side. b) water is the most abundant liquid on earth. c) water bonds with most chemicals. d) water expands as it freezes.

Explanation:

In this case the answer would be

Now since these negative and positives are present in the water molecule . In easy terms when a substance reacts with water .the negative part of water ( oxygen ) reacts with the positive part of the substance and the positive part of the water ( hydrogen) reacts with negative part of the substance .if you look at the reason . Water is held up by one of the strongest attraction forces available .since most substances have weaker attraction forces between them ,therefore water can easily overcome them with its forces. Thus giving it the ability to dissolve a variety of substances
