Answer:
The correct answer is letter "D": One of several products produced from a common input.
Explanation:
Joint products are those manufactured by large companies whose production process is the same at an early stage for all the different products being produced, but at a certain stage, called a split-off, the products begin to have their own characteristics.
Since the products initially come from the same input, the costs are allocated in the bundle. After the split-off, the cost of production is allocated to each type of product.
