What must marketing management consider in relation to a company's product mix or product assortment?

I think option (e) is the right answer. Thank you very much for your help. Regards.

After deploying your marketing mix, segmentation and customer feedback becomes essential. That is why most organizations are deploying a power CRM to track their customer behaviors.

The product assortment falls off the product mix, one is the chicken the other the egg. Keep both in mind.

Simply, the reaction of the target audience to their product mix.

• Point: D, "Product Mix" and " Product Assortment" means the same, and are all the items that you offer. Best thing to consider are: 
• Width
• Length
• Depth

D

length; width; depth

thanks you for your question 

Companies can't neglect neither one nor the other : the phase product mix is essential before the launch of the item to garantee the success of the product. One time, the product is launched the company should consider product assortment : width, lengh, depht.. and it should be noted that your part in the rays of the shops should follows your real market share : for exemple if your market share is 40%, you should negociate not less than 40% of the assortiment in the shops. Thanks.
