Answer:
A). That the index was unlikely to continue going up and that inflation remained.
Explanation:
As per the question, option A displays the sentence that would correctly revise the underlined phrase as it follows parallelism as reflected by the parallel use of 'that' and past tense in both the part of the sentence which the coordinating conjunction 'and' demands. The other options either fail to follow parallelism as the two parts of sentence do not exhibit ideas identically or equivalently(use of 'that' and 'for' in option B and use of 'that' and 'with' in option C) while the other two options employ the incorrect word 'likelihood' and also reflect the misconstruction. Thus, option A is the correct answer.
