Choose the word/ group of a word that has nearly the same meaning as the word/ group of words given: ENCOURAGE 

Concept: Option C: 'Encourage' implies 'to inspire with courage or confidence' or 'to stimulate with help or approval.'

'Stimulate' is defined as 'to stimulate to activity, as by encouragement.'

Hence, option C is right.

Option A: The word 'energize' implies 'to provide energy to.'

Option B: The word 'desire' implies 'to hope for or crave for.'

Option D: Tempt means 'to draw or strongly appeal to.'

These phrases are not synonymous with 'energize,' and stimulate is virtually synonymous with 'encourage.'

As a result, alternatives A, B, and D are incorrect.

Hence, the option C is the correct answer.
