Answer:

option-A

option-D

Step-by-step explanation:

We are given a complex number as

7-\sqrt{3}i

we know that whenever we have

a+bi

where

a is the real number

b is imaginary number

now, we can verify each statement

option-A:

we can see that

a=7

and

a is the real number

so, 7 will be real number

so, this is TRUE

option-B:

we know that

b=-\sqrt{3}

so, imaginary number is -\sqrt{3}

while it is mentioned square root 3 is the imaginary part of the number

so, this is FALSE

option-C:

We can see that coefficient of  i is b

and

b=-\sqrt{3}

so, this is FALSE

option-D:

we know that

'a' and 'b' are sum of real and imaginary number

so, this is TRUE
