Answer:

opption a

Explanation:

because they are telling about same thing

and they both are right

so opption a is correct

Answer 2

The Assertion (A) is Correct :

• Plants require compounds like Amino Acids, Proteins, and Genetic material like DNA for their growth.
• All of these compounds have Nitrogen "N" within them and thus plants require nitrogen for their growth and development.
• But plants cannot consume the atmospheric form of diatomic Nitrogen as they cannot break the triple bond in it.
• Nitrogen-fixing bacteria in the soil decompose and convert this nitrogen into forms of inorganic nitrates and nitrides that can be directly consumed by plants.

The Reason (R) is Correct :

• The various elements that plants require for their growth and development are Nitrogen, Phosphorous, Potassium, Calcium, Magnesium, Manganese, etc.
• Out of all of these, Nitrogen and phosphorus are very crucial for plant nutrition.

Hence, the given Assertion and Reason both are correct.
