Solution : The correct answer is a) Both assertion and reason are true, and the reason is the correct explanation of the assertion.

Horticulture does play a vital role in the export of agricultural products, and the reason for this is that it involves the cultivation of high-value crops that have a significant demand in the international market.

Horticultural crops include fruits, vegetables, flowers, spices, and other specialty crops that are valued for their taste, appearance, fragrance, or medicinal properties. These crops often command higher prices in the international market compared to staple crops.

The cultivation of high-value horticultural crops provides opportunities for export as they cater to the demands of international consumers who seek diverse and exotic produce. Horticultural products are often perishable and require careful handling and transportation to maintain their quality and freshness. As a result, horticulture plays a crucial role in the export of agricultural products.

Many countries, particularly those with favorable climates and suitable growing conditions, have developed a strong horticulture sector to tap into the global market for fresh and processed horticultural produce. These exports contribute significantly to the economy by earning foreign exchange and generating income for farmers and rural communities.

Therefore, the assertion that horticulture plays a vital role in the export of agricultural products is true, and the reason that it involves the cultivation of high-value crops that have a significant demand in the international market is the correct explanation for this assertion.
