Solution

The correct option is A Fabaceae
Root nodules are present on the roots of plants (primarily Fabaceae) which is associated with symbiotic nitrogen-fixing bacteria. Under nitrogen limiting conditions, capable plants form a symbiotic relationship with a host-specific strain of bacteria known as rhizobia. Nodulated roots are characteristic of Fabaceae. The Fabaceae include legume crops such as peas and beans.
So, the correct answer is 'Fabaceae'.
