Solution: The correct answer is Option B: Pithiness . Here's why: * Pithiness means the radish root becomes spongy, less juicy, and develops an undesirable texture. This happens because the plant is putting energy into reproduction (going to seed) instead of keeping the root tender. * Delayed harvesting allows the radish to mature beyond its prime eating stage, leading to this pithiness. Let's look at the other options: * Forking: Forking (splitting into multiple roots) is usually caused by obstacles in the soil or uneven moisture during root development, not delayed harvesting. * Deformed root: Deformed roots can be caused by poor soil conditions, pests, or diseases, but are less directly related to *when* you harvest. * High pungency: While pungency (spiciness) can increase slightly with age, delayed harvesting primarily affects the texture (pithiness) rather than dramatically increasing the pungency. Pungency is more influenced by variety and growing conditions. Therefore, the most direct consequence of delaying radish harvesting is pithiness.

Solution: The recommended storage temperature to extend the shelf life of bananas is 12° - 15°C. Keep them cool and protected from the light: Bananas should be stored at around 13°C, as they will ripen quicker if they are too warm. Bananas grow in hot climates, so they are unused to the cold. If they're kept at a cold temperature in the fridge, the enzymes that enable them to ripen are inhibited. And as those enzymes become inactive, other enzymes operate more efficiently. Some cause cell damage, while others (browning enzymes) cause the skin to blacken.

Solution: An ideal fruit for making jelly should be rich in Pectin and acids. For proper texture, jellied fruit products require the correct combination of fruit, pectin, acid and sugar. Pectin is a substance in fruits that forms a gel if it is in the right combination with acid and sugar. All fruits contain some pectin, but some must be combined with fruits high in pectin or with commercial pectin products to obtain gels. The proper level of acid is critical to gel formation. If there is too little acid, the gel will never set
if there is too much acid, the gel will lose liquid (weep).
