B Correct answer
Explanation

Edible vaccines face challenges with dosage consistency due to variable plant growth conditions, expression levels, and fruit/vegetable size. The other options are actual advantages: therapeutic proteins are pathogen-free, plant tissues are heat-stable (no cold chain needed), and oral vaccines can work despite maternal antibodies (mucosal immunity).
