Concept:This question tests awareness of a recent international event concerning NATO's expansion in 2023.
Explanation:Finland applied for NATO membership in May 2022 following a shift in its security policy.
The application required approval from all existing 30 NATO member nations.
On 4th April 2023, Finland presented its instrument of accession at NATO Headquarters in Brussels, Belgium.
This formal step made Finland the 31st member of NATO.
Italy and Iceland are founding members of NATO from 1949, so they are not new entrants.
Syria has never been a NATO member or applicant.
Hence, Finland is the only correct option.
Answer:Option A: Finland.
