The correct answer is asake. The question is asking for the correct plural form of the noun "Hula-huluna Aska". In Hausa, the plural form
of a noun is typically formed by adding the suffix "-e" or "-i" to the singular form. In this case, the correct plural form of "Aska" is "asake",
The other options - asaku, aska, askoki, and askuna - are not the correct plural forms. Therefore, the correct answer is asake.
