G You need to build a circuit to perform parallel data transfers from one set of registers to another. The interconnections between the registers must be held to a minimum. The best choice for the register FFs is the type.

JK Flip Flop

Explanation:

Flip Flops is a fundamental building blocks of digital electronics systems.  It  is an electronic circuit with two stable states that can be used to store binary data.  However, a JK Flip Flop is a type of universal flip-flop that makes the circuit toggle between two states and is widely used in shift registers.

So when building a circuit to perform parallel data transfers from one set of registers to another, a JK Flip Flop is the best choice he register FFs when you need to hold the interconnection between the register to a minimum.

The best choice for the register FFs  will be the "D" type

Explanation:

The D type Flip flop, also known as the Disabled flip flop. it is the best choice when transferring data between registers. This is because they help prevent unnecessary interconnections between the two registers by using the "SET" and "RESET" features that they have.

If this data input is held HIGH the Disable flip flop would be “SET” and when it is LOW the flip flop would change and become “RESET”.

This helps to avoid problems and interference  when transmitting data between two registers
