When you first started your new business, you were so excited about the large volume of orders you had. one year later, you find that your orders are less than half of what they were in the beginning. what is the most probably cause of this decrease in order? a) you failed to continue your marketing efforts b) you have to much competition c) your price is to high for the market d) you've limited yourself to a small number of products
my guess is (c) or (b) can someone tell me if this is correct? and you.

I would suggest it would most likely to be either A or B or both, however if I had to pick one I would go for A.

A - The question suggests you may have been putting more effort and enthusiasm into sales of the products for your new business "you were so excited about the large volume of orders you had" which may mean after your first year of business you may have started to slack of or get complacent with putting you business out there marketing wise, also when launching a product for the first time people are interested in the new and latest thing (such as a new business) after a while people start to forget unless you have marketing and advertising to remind them.

B - If the product you offer is unique and you were the first business to sale this / these items then after a year it is possible other competitors have started to copy you however this would completely depend on the products you sale.

C - Given you already had large orders in the first year people are happy to pay for the products you offer so this would exclude C.

D - If you have already had many orders in the first year people obviously want the products you sale even if you only sale 1 or 2 things so unlikely to be D.

I’m pretty sure that the answer is d
