William Newman · Answer 1

Option (B) i. e., branch history table is the correct answer to the following question.

Explanation:

In the above question, some part is missing i. e., options which are:

a) look-ahead table

b) branch history table

c) branch prediction table

d) future speculation table

Because the branch history table maintains the records of the previous data or information and instructions also that are used after when it needed in the program or any other fields and it is the table of the shift register. So that's why the following option is correct. it also used design to store the previous data in the shift register.
