A.I. Explanation:

Option 1: "Sports and games generate a feeling of competition in the child and strengthen it."

Explanation: This option misrepresents the author's focus. While it mentions competition, the text emphasizes the lack of sports infrastructure and the absence of sports activities in schools. The author's main concern is not about competition but rather about the deficiencies in the educational system regarding sports.

Option 2: "The schools lack sports infrastructure."

Explanation: Although this statement is true, it does not capture the broader opinion of the author. The text discusses not only the lack of infrastructure but also the implications of this deficiency on child development and education. Therefore, this option is too narrow and does not summarize the author's overall opinion.

Option 3: "School education often fails to cover an important aspect of child education."

Explanation: This option accurately reflects the author's opinion as it encapsulates the main idea of the text. The author highlights the absence of sports and games in schools, indicating that this lack is a significant failure in the educational system. The phrase 'important aspect of child education' aligns with the author's concern about the role of sports in developing essential life skills.

Option 4: "The school curriculum need to be revisited to include sports as an important subject."

Explanation: While this option suggests a solution, it does not accurately summarize the author's opinion. The text does not explicitly call for a revision of the curriculum but rather points out the existing failures in providing sports education. Thus, it presents a solution rather than a summary of the author's expressed concerns.
