How is a strobe signal used when serially loading a shift register?(a)

1.	How is a strobe signal used when serially loading a shift register?(a) To turn the register on and off(b) To control the number of clocks(c) To determine which output Qs are used(d) To determine the FFs that will be usedI have been asked this question in semester exam.My question is based upon Universal Shift Registers topic in chapter Registers of Digital Circuits
Answer» Right option is (b) To CONTROL the number of clocks To explain I would say: A strobe is used to validate the availability of DATA on the data line. It (an auxiliary signal used to help SYNCHRONIZE the real data in an electrical bus when the bus components have no common clock) signal is used to control the number of clocks during SERIALLY loading a SHIFT register.
