(A) are devalued Since the sentence is stating that something has been happening over a past few decades, we cannot use simple present 'are'
(B) are becoming more devalued Same as above. Simple present is used to show regular tasks or continuos tasks eg. A & B are beautiful towns etc.
(C) which have lost valueWhich always refers to the noun preceding it, in this case it would literally refer to south america. Hence illogical choice.
(D) have become devalued use of present perfect: have + past participle. Exactly whats required: a verb tense which shows an action started in past and whose effect continues till present.
(E) have since become devalued
Usage of since is wrong, seems like they have become devalued since past few decades, which is wrong




Hope this helps :)

the action started in the past and ended in the near present whose effect is still present, thus use of present perfect is required...

(A) are devalued (wrong as present tense is used)

(B) are becoming more devalued (present continuous is wrong)

(C) which have lost value (use of "which" is wrong as "which" must be use with "comma" to define the noun touching it---in this case it is south america)

(D) have become devalued (right option)

(E) have since become devalued
(since is wrong...since when? its already given that "over the past few decades)

More clearly, the word since is used to depict a point in time, not a period of time.

WE have to review grammar a little bit.
simple present is used to show a condition which is thought to exist indefinitely. it dose not exist in a period. "over the past few decades" can not go with simple present.
"over last few decades" is unfinished period, which prolong from a point in the past to present. normally , this time word go with present perfect.
"over last few decades" can be finished time period, which prolong from a point in the past to another point in the past. in this case, simple past is used.
