Final answer:
Reciprocating pumps are known to create the greatest suction lift among positive displacement pumps due to their mechanism of creating a vacuum through the movement of pistons, plungers, or diaphragms.
Step-by-step explanation:
The type of positive displacement pump that creates the greatest suction lift is the B) reciprocating pump. Reciprocating pumps use pistons, plungers, or diaphragms that move back and forth to create a vacuum, which enables them to generate a significant suction lift. These pumps are capable of creating a stronger vacuum than rotary, centrifugal, or turbine pumps and are commonly used for applications that require high suction lift.
