Answer 1

The correct option is B fasciculated roots

Nodulose roots: These modified adventitious roots become swollen only at their tips due to accumulation of food, e.g: Roots of Maranta.

Fasciculated roots are a type of modified adventitious roots which occur in clusters at the base of the stem and become thick due to storage of food, e.g: Asparagus, Dahlia.

Beaded roots, also known as moniliform roots: These are swollen at intervals like a beaded necklace, eg: Indian spinach, some grasses.

Annulated roots: These modified adventitious roots posses a ring like out growth appearing like a disc one above the other, eg: Carapichea ipecacuanha.
