Fill in the blank with a suitable preposition.
The memento was given _______ honour his contribution to the project.
The preposition ‘to’ is used to refer to the person/thing that receives something, i.e. the receiving end. In addition to this, it is also used especially while referring to giving something ‘in honour of' an action. In the given sentence the person gets the memento for his contribution. Thus option A is correct. Whereas ‘towards’ is used to denote a direction which is irrelevant here, therefore, option B is incorrect. On the other hand, ‘with’ and ‘at’ are inappropriate here because ‘with’ is used to refer to a tool or to denote company, while ‘at’ refers to a place. Both of these are unsuitable here as 'honour' is not a tool or a place, so options C and D are incorrect.
