Explanation:

Rhizobium is a soil bacteria that fixes nitrogen, so it can’t manufacture food. Hence, statement 2 is incorrect.
Only plants are capable of growth through vegetative propagation (i.e. growing another full plant with parts of a plant). Hence, statement 3 is incorrect.
Learning: Both bacteria and blue-green algae can fix nitrogen directly from the atmosphere, but this is less vital to plant development than the symbiotic relationship between the bacteria genus Rhizobium and leguminous plants and certain trees and shrubs.
Some nitrogen-fixing bacteria, such as Azotobacter, Clostridium pasteurianum, and Klebsiella pneumoniae, are free-living, whereas species of Rhizobium live in an intimate association with leguminous plants. Rhizobium organisms in the soil recognize and invade the root hairs of their specific plant host, enter the plant tissues
In return for secretions (food) from their host that encourage their growth and multiplication
