Analyze the question stem: If m, n, and p are all digits greater than 1 and their sum is also a digit, what is the value of m?
That means the sum of m,n, and p is a single digit as well. This is only possible with 9 being the sum of digits.
Case I: m, n, and p are all distinct -> M can be 2 or 3 or 4 (No def. answer)
Case II: m is largest -> clearly insufficient
Case I&II together -> M is 4. N&P can be 2 or 3 or vice versa
Hence C
