I think that A could be the answer, and I've seen other people choose that too, but I want to know the evidence and if it is correct.

Answer 1

A = water is an excellent solvent.

Step-by-step explanation:

What is solvent:

Solvent is the that part of solution which is present in large proportion and have ability to dissolve the solute.

Step-by-step explanation:

In simplest form solvent is something in which other substance get dissolve. The most widely used solvent is water, other examples are toluene, acetone, ethanol, chloroform etc.

Water is called universal solvent because of high polarity all polar substance are dissolve in it. Hydrogen is less electronegative while oxygen is more electronegative and because of difference in electronegativity hydrogen carry the partial positive charge while oxygen carry partial negative charge.

Water create electrostatic interaction with other polar molecules. The negative end of water attract the positive end of polar molecules and positive end of water attract negative end of polar substance and in this way polar substance get dissolve in it.

Example:

The minerals and nutrients in our body dissolved in water and transported through out the body.
