Answer is Right!
The correct answer is: A. 5
Murray code is a five-bit code used for telegraphy. It was developed in 1901 by Donald Murray, a Scottish engineer. Murray code was the first code to use five bits per character, which allowed for more characters to be represented than previous codes. Murray code was widely used in telegraphy until the 1970s, when it was replaced by Baudot code.
Option B is incorrect because Murray code uses five bits per character, not six.
Option C is incorrect because Murray code uses five bits per character, not nine.
Option D is incorrect because Murray code uses five bits per character, not 25.
Option E is incorrect because Murray code is a five-bit code.
