The question was posed to me in homework.

Answer 1

Right option is (b) fetchrow_arrayref()

Easy explanation: ‘fetchrow_arrayref()’ returns a reference to an array of row values. The function ‘fetchrow_hashref()’ returns reference to hash of row values. ‘fetch()’ is the same as fetchrow_arrayref().
