• B. 1,2 and 4
• C. 1,3 and 4
• D. 2,3 and 4

Answer 1

The Correct Option is B

Geometric Terms Analysis 

Step 1: Relationship between Sector, Chord, and Diameter

Sector: A sector is a part of a circle.

Chord: A chord is a straight line connecting two points on a circle.

Diameter: A diameter is a straight line passing through the center of the circle and touching two points on the circle.

Step 2: Analyzing Diagonal

Diagonal: A diagonal, on the other hand, is not specific to circles; it refers to a line connecting two non-adjacent vertices of a polygon.

Step 3: Conclusion

Therefore, the correct group consists of 1, 2, and 4.
