English grammar — sentence improvement (reported achievement): Decide whether the original sentence requires correction. Original sentence: "The police has so far succeeded in recovering only a part of the stolen property." Choose the option that best improves (or confirms) the sentence.

Given data

• Structure: Present perfect progressive sense with "has so far succeeded in + -ing".
• Object: "only a part of the stolen property".

Concept/Approach
The idiom is "succeed in + gerund". "So far" is the standard time adjunct. While many style guides prefer plural agreement "police have" (treating "police" as a plural collective), exam conventions sometimes accept institutional singular. The alternatives offered are ungrammatical or non-idiomatic.

Option analysis
A. "thus far succeeded for recovery" → wrong preposition and noun form.B. "succeeded in recovery of" → wordy/awkward nominalization.C. "as for as" → incorrect phrase; should be "as far as".D. "succeeded to recover" → wrong verb pattern; should be "succeeded in recovering".E. "No correction required" → best among given options.

Note on agreement
In many dialects, "The police have..." is preferred; however, within this item's choices, grammar and idiom favor the original.

Final Answer
No correction required
