algol [13]

Answer:

B. Do not need much water, so they prefer soil that drains the water.

Explanation:

Sandy soil is one of the three basic soil types we have in nature (the others being loamy soil and clayey soil). One of the properties of the Sandy soil is its high water draining ability i.e. it has a low water holding capacity. This draining characteristics is due to the large pores that Sandy soils possess.

According to this question, three plants namely: yarrow, bearded iris, and sea oats grow best in sandy soil. This indirectly means that these plants mentioned do not need much water for their growth since they grow best in a soil that drains water efficiently.
