World Intellectual Property Day is observed every year on which date?

Introduction / Context:
World Intellectual Property Day is an annual observance that highlights the role of intellectual property in encouraging innovation and creativity. It is celebrated on 26 April, the date on which the convention establishing the World Intellectual Property Organization entered into force. Competitive exams frequently include this date among important international days related to science, technology, business and law.

Given Data / Assumptions:
- The observance in question is World Intellectual Property Day.
- The task is to identify the correct fixed calendar date on which it is observed.
- All options lie in late April, making it necessary to know the exact day rather than just the month.

Concept / Approach:
To answer, you need to connect intellectual property and WIPO with the specific date 26 April. One effective memory technique is to assign themes to parts of the month: for example, Earth Day on 22 April and Intellectual Property Day on 26 April, both occurring in the final third of the month. Recognizing that these days are relatively close together can help you remember their exact ordering.

Step-by-Step Solution:
Step 1: Focus on the phrase “World Intellectual Property Day” in the question. Step 2: Recall that the day is tied to WIPO and is celebrated on 26 April each year. Step 3: Scan the answer choices for 26 April. Step 4: Notice that other options like 23 April or 22 April are associated with different observances, such as World Book and Copyright Day or Earth Day. Step 5: Select 26 April as the correct answer, since it uniquely matches World Intellectual Property Day.

Verification / Alternative check:
As a quick alternative check, recall that 22 April is Earth Day, focusing on environmental protection. Similarly, 23 April is World Book and Copyright Day, related to literature and publishing. The remaining key date in late April linked with innovation, patents, trademarks and copyrights is 26 April, confirming it as the date for World Intellectual Property Day.

Why Other Options Are Wrong:
27 April: Not recognized as the official date of this observance and is less prominent in general GK calendars.
24 April: Associated with different historical events and not with intellectual property as a global theme.
25 April: Known for other observances in some countries but not for World Intellectual Property Day.
23 April: Linked to World Book and Copyright Day, which is related to literature and publishing, not the broader intellectual property system celebrated on 26 April.

Common Pitfalls:
Because many UN and international days cluster in April, students often confuse Earth Day, Book and Copyright Day and Intellectual Property Day. Another common issue is to misremember whether the correct date is the 25th or 26th. To avoid this, build a mini chain in your memory: 22 April for Earth, 23 for Book and Copyright, and 26 for Intellectual Property. This ordered sequence reduces confusion and improves recall in exams.

Final Answer:
Correct option: 26 April
