Answer:
1 < x < 7.5
Step-by-step explanation:
This problem can be solved using given below property of triangle.
Sum of two sides is always greater than third side of triangle.
Difference of two sides is always lesser than third side of triangle.
_______________________________________________
Given
sides length 
6.5 units
3.5 units
Third side is 2.5 +  x
using the property, Sum of two sides is always greater than third side of triangle.
6.5 + 3.5 > 2.5 +x 
=>10 >2.5 + x
=>2.5 + x< 10
=> x< 10 -2.5
=> x < 7.5
using the property, Difference of two sides is always lesser than third side of triangle.
6.5 - 3.5 >  2.5 +x 
=>3.5 >  2.5 +x 
=> 2.5 +x  > 3.5
=> x  > 3.5 - 2.5
=> x  > 1
combining both we have
1 < x < 7.5
 
out of the given option none is 1 < x < 7.5
hence, correct answer will be 1 < x < 7.5 and wrong option can be claimed by student.
