What does the acronym 'M.A.D.HORSE' represent in tree terminology?

Types of fruits
Tree planting seasons
Opposite leaf arrangement
Soil composition

The correct answer is: Opposite leaf arrangement

M.A.D.HORSE stands for mnemonic device to help memorize the types of opposite leaf arrangement in trees, which are Mixed, Alternate, Decussate, Whorled, Opposite, and Scattered. This acronym does not represent any other options, such as types of fruits, tree planting seasons, or soil composition. The other options are not relevant to M.A.D.HORSE, as they are not related to tree terminology.
