Which of the following is the disadvantage of reciprocating pump used

1.	Which of the following is the disadvantage of reciprocating pump used in liquid chromatography?(a) Produces pulsed flow(b) Corrosive components(c) Does not have small hold-up value(d) Does not have moderate flow rateI got this question in unit test.My doubt is from Liquid Chromatography in section Chromatography of Analytical Instrumentation
Answer» The CORRECT choice is (a) PRODUCES pulsed flow Explanation: The disadvantage of reciprocating pump used in LIQUID chromatography is that it produces pulsed flow. THEREFORE, the flow must be damped before it affects the column.
