9) All of the following changes may indicate a change in product classification of a manufacturingprocess which has a splitoff point EXCEPT a:A) byproduct increases in sales value due to a new applicationB) main product becomes a joint productC) main product becomes technologically obsoleteD) byproduct loses its market due to a new inventionAnswe

The question is asking which of the given options does NOT indicate a change in product classification of a manufacturing process which has a split-off point.

A) A byproduct increases in sales value due to a new application - This would indicate a change in product classification as the byproduct could potentially become a main product due to its increased value.

B) Main product becomes a joint product - This also indicates a change in product classification as the main product is no longer the sole product but is now produced jointly with another product.

C) Main product becomes technologically obsolete - This would indicate a change in product classification as the main product may no longer be viable to produce and sell.

D) Byproduct loses its market due to a new invention - This does NOT necessarily indicate a change in product classification. While the byproduct may lose its market, it doesn't necessarily change its classification in the manufacturing process. It remains a byproduct, albeit one that is less valuable or potentially worthless.

So, the answer is D.
