Topic: Adjective (বিশেষণ),

Best Answer Explained in Below-:

The sentence "We had tasty and __ meals." requires an adjective that describes the meals in a complementary manner to "tasty." The correct answer, "nutritious," is an adjective that specifically conveys that the meals provide health benefits, containing essential nutrients that support well-being.

Option A, "nutritious," is the most appropriate choice because it directly modifies "meals" to indicate that they are healthy and beneficial to eat. It forms a natural combination with "tasty," suggesting that the meals are both enjoyable and good for health, which is a desirable trait in food.

Option B, "nutritional," refers to the related qualities of nutrients or the process of providing nutrition, but it is less commonly used directly to describe meals. Option C, "nutritive," has a similar meaning to "nutritious" but is less frequently used in everyday language to describe meals. Lastly, option D, "nutrient," is a noun and cannot appropriately fit in the blank, as the sentence structure needs an adjective.

In summary, "nutritious" perfectly complements "tasty" while effectively describing the meals in both flavor and healthiness, making it the correct choice.
