2. Only four
3. Only three
4. Only two

Explanation

Option (b) is correct

• A time zone is a region of the Earth that observes a uniform standard time for legal, commercial, and social purposes. Time zones are generally based on the position of the Sun relative to the Earth and are defined in relation to Coordinated Universal Time (UTC). The Earth is divided into 24 time zones, each approximately 15° of longitude apart, corresponding to a 1-hour difference from UTC. Some countries, such as China and India, use a single time zone for their entire territory, even though they span several degrees of longitude. Other countries, such as Russia and the United States, use multiple time zones to accommodate their large size and diverse regions.
• The United Kingdom (9 time zones), Denmark (5 time zones), New Zealand (5 time zones), and Australia (9 time zones) have more than four time zones, while Brazil has exactly four.
