Solution

The correct option is B non-stoichiometric hydrides.
Non- stoichiometric hydrides are formed by many d-block and f-block
elements.  they are almost always nonstoichiometric, being deficient in hydrogen. 

For example, $$LaH_{2.87}$$ , $$YbH_{2.55}$$, $$TiH_{1.5–1.8}$$, $$ZrH_{1.3–1.75}$$, $$VH_{0.56}$$, $$NiH_{0.6–0.7}$$, $$PdH_{0.6–0.8}$$ etc.

In such hydrides, the law of constant composition does not hold good.
The property of absorption of hydrogen on transition metals is widely used in catalytic reduction/hydrogenation reactions for the preparation of a large number of compounds.

Some of the metals (e.g., Pd, Pt) can accommodate a very large volume of hydrogen and, therefore, can be used as its storage media. This property has a high potential for hydrogen storage and as a source of energy.

Hence, the correct option is C
