Such as is used for specific examples and to introduce clauses and like is used for generalities and to compare nouns. In addition you need remains on the end of the underlined portion becuse it goes with the noun the market.

Option A. commodities like aluminum and other metals remain'
This answer looks correct but check 'remain' it is supposed to be in singular which is 'remains' because it is a verb of the subject 'The market'.

Option B.
B. commodities like those of aluminum and other metals are remaining
This option looks incorrect on its own because literally,the commodities they were referring to was of aluminium and other metals and not of 'those of aluminium'

Option D. commodities, such as aluminum and other metals, remain

This option is similar to option C but becareful of 'remain' it is in its plural form and it is supposed to be a verb of the subject 'The market'

Option E. commodities, like the commodities of aluminum and other metals, remains
This is definitely an incorrect statement and it is also guilty of tautology .

Option C. THIS IS THE CORRECT ANSWER!!!!!.
commodities such as aluminum and other metals remains
this option clearly shows and explain what other options could not point out and remember that 'such as' is chosen over because such as is used for specific examples and to introduce clauses also remains is chosen over 'remain' in option D because we strongly consider our subject 'The market' which is a singular noun.Therefore, option C is right.
