What could be one practical reason for retaining a colonial language in national language policy?

Correct answer: Its use in higher education administration and international contact

A country may retain a colonial language for practical reasons even while strengthening its own national and local languages. A language already used in universities, courts, administration, science, or international communication can provide a common working medium in a linguistically diverse country. Retaining it does not automatically mean accepting colonial rule or rejecting national identity.

Option A gives a realistic reason: the language may remain useful in higher education, government administration, and communication beyond the country. The absence of local languages is false because most colonized societies have rich linguistic traditions. Colonial power need not return, and national identity does not end merely because a foreign language is used. Therefore, option A is correct.
