The range of standard current signal in process instruments is 4 to 20 mA. Which ONE of the following is the reason for choosing the minimum signal as 4 mA instead of 0 mA?
(A) To minimize resistive heating in instruments,
(B) To distinguish between signal failure and minimum signal condition
(C) To ensure a smaller difference between maximum and minimum signal
(D) To ensure compatibility with other instruments.
