A Correct answer
Explanation

cin.getline() takes parameters in order: buffer pointer, maximum characters, and delimiter. Option A cin.getline(x, 100, '\n') is correct - x is the character array, 100 is max chars, \n is the delimiter. Option B swaps the first two parameters incorrectly. read() and readline() are not standard C++ functions.
