aluminium and other metals are just 'metals" not recycled commodities, we do not therefore need the "such as"

we are comparing the market for recycled commodities to the market for metals. so E is correct.

Thanks Scooby. Can you please help me understand why "like" is correct in "E" and why"such as" is not required in "E"? As per my understanding
Like = similar to.
such as = for example.

Also. can you please help me understand the following:

Let's say the word "recycled" would not have been there in the below question, then which one would have been correct:

The market for commodities like aluminum and other metals remain strong despite economic changes in the recycling industry.

A. commodities like aluminum and other metals remain
B. commodities like those of aluminum and other metals are remaining
C. commodities such as aluminum and other metals remains
D. commodities, such as aluminum and other metals, remain
E. commodities, like the commodities of aluminum and other metals, remains

I don't quite get this..Where we are comparing two markets in option E?

The market for commodities, like the commodities of aluminum and other metals, remains strong despite economic changes in the recycling industry.

Don't you think we are giving example of particular type of commodities and should use 'such as' in place of 'like' ??
