The correct answer is D. revenue mix allocation method.
The revenue mix allocation method is a method of allocating bundled revenues for each product in a bundle. It uses specific information on products as weights to allocate the revenues. This method is more accurate than the other methods, as it takes into account the specific characteristics of each product.
The step down allocation method is a method of allocating bundled revenues for each product in a bundle. It allocates the revenues in a step-wise manner, starting with the product that has the highest revenue. This method is not as accurate as the revenue mix allocation method, as it does not take into account the specific characteristics of each product.
The stand-alone revenue allocation method is a method of allocating bundled revenues for each product in a bundle. It allocates the revenues based on the stand-alone revenues of each product. This method is not as accurate as the revenue mix allocation method, as it does not take into account the synergies between the products in the bundle.
The incremental revenue allocation method is a method of allocating bundled revenues for each product in a bundle. It allocates the revenues based on the incremental revenues of each product. This method is not as accurate as the revenue mix allocation method, as it does not take into account the cannibalization between the products in the bundle.
