Fill in the blank with a suitable preposition.
Sugar is extracted _______ sugarcane.
The preposition ‘from’ is used to refer to where something is derived or originated from. In the gives sentence sugar is derived from sugarcane, i.e. sugarcane is the source/raw material from which we get sugar. Hence option C is correct. Whereas ‘to’ is used to refer to the receiving end or the destination of something, which is the opposite of what the sentence attempts to convey. Therefore option B is incorrect. On the other hand ‘on’ and ‘for’ are unsuitable here. ‘On’ is used to refer to a surface or place; while ‘for’ is a preposition of reason that denotes the purpose of an action. In the given context both of these are irrelevant. The 'sugarcane' is neither a surface/place where the extraction takes places nor the reason why sugar is extracted. Hence options A and D are incorrect.
