keywords: 

{'deccan traps': [0, 0, 0, 1], 'cretaceous period': [0, 0, 0, 1], 'volcanic lava': [0, 0, 0, 1], 'regur soil': [0, 0, 0, 2], 'intense volcanic activity': [0, 0, 0, 1], 'fissure eruption': [0, 0, 0, 1]}

The correct answer is option 1, which states that statements 1 and 2 are correct.

Statement 1 is correct because intense volcanic activity in the form of fissure eruption did indeed take place towards the end of the Cretaceous period. This volcanic activity led to the formation of the Deccan Traps in India.

Statement 2 is also correct because the volcanic lava from the Deccan Traps did spread out in horizontal sheets. The lava flows covered a large area and formed a series of basaltic layers that make up the Deccan Traps.

However, statement 3 is incorrect. The regur soil found in the Deccan Traps is not rich in nitrogen. Regur soil, also known as black soil, is known for its fertility and high clay content, but it is not specifically rich in nitrogen.

Therefore, while statement 1 and statement 2 are correct, statement 3 is incorrect. Alert - correct answer should be option 1 and 2 only.
