Best answer
The correct option is (a) Does not allow accumulation of products

Explanation: It’s a difficult task to control the pH of packed bed bioreactors by the adding acid or alkali because of poor mixing. These bioreactors are preferred for bioprocessing technology involving product-inhibited reactions since the packed bed bioreactors does not allow accumulation of the products.
