The correct option is C Honey is made by bees by digesting pollen collected from flowers.
Odour
Flowers which are pollinated by flies and bats produce an odour to attract them as these insects mostly feed on animal faeces and wastes.
Honey production
Regurgitation and evaporation are used to create honey from nectar. Saccharides (carbohydrates) are converted to honey by honey bees regurgitating them several times until they are half digested.
Because the aqueous solution is still rich in water after the last regurgitation, the process continues with evaporation of much of the water as well as due to mouth-to-mouth transfer by the bees.
Pollen tablets and syrups
Pollen tablets and syrups are used as health supplements because the pollen grains are a good source of carbohydrates, fats and proteins.
Pollen allergy
Pollen allergy is caused by pollen of some plant species that results in hay fever, asthma and bronchitis in some individuals.
Final answer
(B) Honey is made by bees by digesting pollen collected from flowers.
