In a competitive market, ………. :

“It is considered to be essential the reliable suppliers.”

• This sentence is grammatically incorrect and awkwardly structured. The placement of “the reliable suppliers” at the end disrupts the flow of the sentence.

“Reliable suppliers are considered to be essential.”

• This sentence is clear, direct, and grammatically correct. It effectively communicates the importance of reliable suppliers in a competitive market.

“Reliable suppliers consider them essential.”

• This sentence is grammatically correct but unclear. It suggests that reliable suppliers consider something else to be essential, rather than highlighting the importance of reliable suppliers themselves.

Overall, the second option is preferred because it clearly and accurately conveys the importance of reliable suppliers in a competitive market.
