A recent court decision has qualified a 1998 ruling that workers cannot be laid off if they have been given reason to believe that their jobs will be safe, provided that their performance remains satisfactory. (A) if they have been given reason to believe that their jobs will

(B) if they are given reason for believing that their jobs would still

(C) having been given reason for believing that their jobs would

(D) having been given reason to believe their jobs to

(E) given reason to believe that their jobs will still

(A) if they have been given reason to believe that their jobs will

Explanation:

Option A is correct because it has 'if' a conditional clause that uses present perfect tense which should be followed by the main clause ''will''.

We can not use 'would' as an answer when there is a clear condition and we are certain of its prediction. This would make option B incorrect. The other options are also wrong, because the conditional statement 'if' is required based on the fact that that the court qualified a ruling that workers cannot be laid off.

(A) if they have been given reason to believe that their jobs will

Explanation:

The most appropriate answer choice is "if they have been given reason to believe that their jobs will" because this entails on an ongoing basis the workers are well assured that their jobs will be safe and secure.
