A. ord()
B. ord(‘ ‘)
C. ord(”)
D. ord(“”)

Solution

B. ord(‘ ‘)

Explanation

The function ord() accepts a character. Hence ord(), ord(”) and ord(“”) throw errors. However the function ord(‘ ‘) does not throw an error because in this case, we are actually passing a blank space as an argument. The output of ord(‘ ‘) is 32 (ASCII value corresponding to blank space).
