B Correct answer
Explanation

Dahlia has fasciculated roots, which are characterized by a cluster of swollen tuberous roots arising from the base of the stem. Unlike single tuberous roots (like in sweet potato), fasciculated roots form a bunch-like structure. This is a specialized adventitious root modification for food storage.
