Answer:

C. 21

21

Step-by-step solution using the BODMAS/PEMDAS rule:

1. Division (÷):
   27 ÷ 9 = 3
   The expression becomes: 3 + 6 × 4 - 6

2. Multiplication (×):
   6 × 4 = 24
   The expression becomes: 3 + 24 - 6

3. Addition (+):
   3 + 24 = 27
   The expression becomes: 27 - 6

4. Subtraction (-):
   $27 - 6 = \mathbf{21}$
