Introduction:
The Tropical Monsoon Climate is characterized by distinct wet and dry seasons. In this climate, a significant amount of rainfall is concentrated within the rainy season, which is responsible for the majority of the annual precipitation.

Explanation:
The percentage of annual rainfall concentrated within the rainy season in the Tropical Monsoon Climate is high, and option 'C' (95%) is the correct answer. This means that 95% of the total annual rainfall occurs during the rainy season.

Factors contributing to concentrated rainfall:
Several factors contribute to the concentration of rainfall within the rainy season in the Tropical Monsoon Climate. These factors include:

1. Monsoon Winds: The monsoon winds are a dominant feature of the Tropical Monsoon Climate. These winds blow from the cold landmass to the warmer oceans during the summer season, bringing moisture-laden air. This moisture condenses and leads to heavy rainfall during the rainy season.

2. ITCZ (Inter-Tropical Convergence Zone): The Intertropical Convergence Zone is a belt of low pressure near the equator where trade winds converge. It is associated with abundant rainfall. During the rainy season, the ITCZ shifts towards the region, resulting in increased rainfall.

3. Topography: The presence of mountain ranges or elevated terrains can enhance rainfall in the Tropical Monsoon Climate. Mountains act as barriers to the monsoon winds, forcing them to rise and cool, which leads to the formation of clouds and precipitation.

4. Sea Surface Temperature: The temperature of the sea surface plays a crucial role in the formation of monsoons. Warmer sea surface temperatures provide more moisture to the air, resulting in increased rainfall during the rainy season.

Conclusion:
To summarize, the Tropical Monsoon Climate experiences a concentrated amount of rainfall within the rainy season. Approximately 95% of the annual rainfall occurs during this period due to factors such as monsoon winds, the ITCZ, topography, and sea surface temperature. It is important to understand these climatic patterns to effectively manage water resources, agriculture, and other sectors dependent on rainfall in regions with a Tropical Monsoon Climate.
