Explanation

The key here is to consider total time zones including overseas territories, not just mainland geography.

United Kingdom – Correct. Although mainland UK has one time zone, its overseas territories (like Bermuda, Falklands, Gibraltar, Pitcairn Islands) span more than four time zones.

Denmark – Correct. Mainland Denmark has one time zone, but with Greenland (multiple zones) and Faroe Islands, it extends to more than four time zones.

New Zealand – Correct. Beyond mainland NZ, territories like Chatham Islands, Tokelau, Cook Islands expand it to more than four time zones.

Australia – Correct. Mainland has three time zones, but including external territories (Christmas Island, Cocos Islands, Norfolk Island), it exceeds four time zones.

Brazil – Incorrect. Brazil spans exactly four time zones, not more than four.

Thus, four countries have more than four time zones.
