- Solar Radiation Modification: This refers to the intentional modification of Earth's shortwave radiative budget with the aim of reducing warming.
- Ocean Fertilisation: Deliberate increase of nutrient supply to near-surface Ocean to enhance biological production through which additional carbon dioxide from the atmosphere is sequestered. This can be achieved by the addition of micro-nutrients or macro-nutrients. Ocean fertilisation is regulated by the London Protocol.

Statement Analysis
The given statements are related to two different techniques used to address global warming, namely Solar Radiation Modification and Ocean Fertilisation. Let's analyze each statement individually:
1) ‘Solar Radiation Modification’ refers to the intentional modification of Earth's longwave radiative budget with the aim of reducing warming.
This statement is correct. Solar Radiation Modification refers to the deliberate alteration of the amount or characteristics of solar radiation reaching the Earth's surface. This can be done by various methods such as increasing the reflectivity of the Earth's surface, or by injecting reflective particles into the upper atmosphere. The aim of this technique is to reduce the amount of solar radiation that is absorbed by the Earth's surface, thereby reducing warming.
2) Ocean fertilisation is a deliberate increase of nutrient supply to near-surface Ocean to enhance biological production.
This statement is also correct. Ocean Fertilisation is a technique used to increase the productivity of the oceans by adding nutrients such as nitrogen and phosphorus to the surface waters. This stimulates the growth of phytoplankton, which in turn increases the availability of food for marine organisms. The aim of this technique is to enhance the biological productivity of the oceans, which can help in sequestering carbon dioxide from the atmosphere.
Answer Explanation
Both statements are correct, but the question asks for the statement(s) that are correct. Therefore, the correct answer is option 'B', which states that only the second statement is correct.
