Given data:
- Efficiency of fill pipe A = 4 times efficiency of fill pipe B
- Time taken by fill pipe A = 33 minutes less than fill pipe B

Let's assume:
- Efficiency of fill pipe B = x cisterns filled per minute
- Efficiency of fill pipe A = 4x cisterns filled per minute

Time taken by fill pipe B:
- Let the time taken by fill pipe B be t minutes
- Therefore, the time taken by fill pipe A = t - 33 minutes

Combined efficiency:
- Combined efficiency of both pipes = x + 4x = 5x cisterns filled per minute

Time taken to fill the cistern:
- Time taken to fill the cistern when both pipes are opened together = 1 / 5x minutes

Equation:
1 / 5x = t
1 / 5x = t - 33

Solving the equation:
- From the equations, we get t = 8.8 minutes

Therefore, the cistern will be full when both pipes are opened together in 8.8 minutes. Hence, the correct answer is option A) 8.8 minutes.
