Answer
The correct option is D, which is:
$$ 55x  x^2 $$
To explain further:

Let the number of toys produced on that day be denoted by ( x ).

The cost of production for each toy (in rupees) on that day is given by ( 55  x ).

Therefore, the total cost of production (in rupees) for ( x ) toys is calculated as:
$$ x \times (55  x) = 55x  x^2 $$
Thus, the total production cost in terms of ( x ) is ( 55x  x^2 ), matching option D.
