Answer choice: [B] or [C]; could be considered correct; depending on the perspective (explained below).
Personally, I would go with: Answer choice: [C]: "74" ; because:
1) It's an easier number to "work with" than "Answer choice: [B]: "73.9" ; and:
2) The question asks to "estimate the answer".

One interpretation would be:
______________________________
Consider the math problem given:
________________________________
" 471.41 – 397.46 = ? " ;
_____________________________
And round each of THESE values to the nearest TENTH:
________________________________________________
471.4 – 397.5 = 73.9 ; this answer: "73.9" ; is already rounded to the nearest "tenth"; and does correspond with answer choice: [B].

Yet, answer interpretation of this math problem, would be:
____________________________________________________
Given: "471.41 – 397.46 = ?? " ;
________________________________
Solve this problem as it is; and round the actual answer obtained to the nearest "tenth":
___________________________________________
Doing so, we get:
___________________________________________
"471.41 – 397.46 = 73.95 ." This value, rounded to the nearest "tenth", would be: "74.0" (which is not an answer choice, technically speaking); or "74" (because, in "mathematics", "74.0 = 74"; and we are asked in the problem to "estimate for the answer", so the answer would be:
Answer choice: [C]: 74 .
