D Correct answer
Explanation

In dicots, the most common type of pollen tetrad arrangement is tetrahedral, where the four microspores are arranged in a three-dimensional pyramid-like structure. This occurs when microspores divide in all planes. Isobilateral is more common in monocots, while linear and decussate are less frequent patterns.
