Answer: The correct option is
(A) -9 + 9i.
Step-by-step explanation: We are given to find the value of the following expression :
[tex]E=(-7+3i)-(2-6i)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
We will be using the following property of complex numbers :
[tex](a+bi)-(c+di)=(a-c)+(b-d)i.[/tex]
Therefore, from expression (i), we get
[tex]E\\\\=(-7+3i)-(2-6i)\\\\=(-7-2)+(3-(-6))i\\\\=-9+(3+6)i\\\\=-9+9i.[/tex]
Thus, the required value of the given expression is -9 + 9i.
Option (A) is CORRECT.
