Show answer and explanation

Correct answer: (B) 1–c,2–d,3–a,4–e,5–b

Explanation

A tensiometer characterizes soil-water suction; a piezometer measures pressure head; a lysimeter determines consumptive water use; an elbow meter measures flow through differential pressure; and a Pitot tube uses the stagnation/static-pressure relation from Bernoulli. The intended mapping is **B**. Soil moisture in c refers to moisture condition/potential, not a direct volumetric reading.
