Select the most appropriate option to fill in blank number 1.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. presence.
The sentence "The roots of some plants get swollen with the (1) __________ of storage food..." needs a word that indicates that storage food is present in the roots. The word "presence" fits best here, as it means the state of being present or existing in a particular place.
Why the other options are incorrect:
"Occupancy" refers to someone using or living in a space—irrelevant in this biological context.
"Residence" refers to a place where someone lives, not suitable for describing food in plant roots.
"Existence" is vague and general; it doesn't specifically convey that food is located in the roots.
