Select the option that contains a grammatical error in the highlighted portion.
There are three cupholders placed on the cupboards of the secretariat table.

Correct option is B

Option (b) contains an error.

Error: Use of ‘on the cupboards’ is incorrect.
Correct usage: Should be ‘in the cupboards’.

Explanation:

• The preposition ‘on’ means on the surface.
• The word ‘in’ is used when something is enclosed or inside a container/space like cupboards.
• Hence, cupholders being placed inside cupboards requires "in".

Grammatical Rule Used:
Prepositions of place:

• on = on surface
• in = inside something enclosed
• at = at a point

Example: The keys are in the drawer, not on the drawer.

Information Booster: Always check the noun involved; closed structures (box, cupboard, bag) typically take “in.”
