Final answer:
Perennial Ryegrass has a bunch-type growth habit and grows in clumps without horizontal spreading, making it the correct answer to the question.
Step-by-step explanation:
The grass that has a bunch-type growth habit is Perennial Ryegrass (Answer D). Bunch-type grasses grow upright and do not spread laterally by runners or rhizomes. Kentucky bluegrass, for instance, has a spreading growth habit through rhizomes. Zoysiagrass and St. Augustinegrass both spread by stolons, and thus, do not exhibit a bunch-type growth habit. This means {Perennial Ryegrass} is the correct choice, as it grows in bunches, and it is known for its clumping growth, which does not typically involve spreading horizontally across the ground.
