I believe the answer is D.
The statement that describes what makes a base weak is that the base will be unable to dissociate completely in water.
<h3>What is a base?</h3>
A base is any of a class of generally water-soluble compounds, having bitter taste, that turn red litmus blue, and react with acids to form salts.
Bases usually dissociate into hydroxide ions (OH-) when in an aqueous solution.
However, a base is termed weak or strong depending on it's ability to dissociate completely. A weak base does not dissociate completely into hydroxide ions when in an aqueous solution.

Answer:

Explanation:
Hello,
In this case, the first step is to compute the difference in the electronegativity for the formed bond between gallium and phosphorous by:

Thus, we can compute the percentage of ionic character by:

So the fraction is just:

Which has sense since gallium phosphide is a non-polar compound.
