Where is the error here (TMS Quanti)?

According to the solutions, D would be correct

My approach to the solution was that the amount of liters is inversely proportional to the bacterial concentration, which is why I used the formula for antiproportionality.

⇒ The more L, the lower the bacterial concentration

But my concentration for A (should be the same as with B) is too low according to the solution.

Can't read your writing.

For me, after tilting and dilution to 600 ml, this is 0.6 a / 3 and 0.6 b / 3 bacteria. 0.6 a / 3 / 6 = a/30 and b/30, ie answer (C), is then reduced to 100 ml.
