Let's solve the problem step by step.
1. We start by identifying the number of fans Rose has, which is given as [tex]\( m \)[/tex].
2. The problem states that Rob has 93 fewer fans than Rose. This means we need to subtract 93 from the number of fans Rose has.
3. The expression to determine how many fans Rob has is the number of fans Rose has, [tex]\( m \)[/tex], minus 93.
Thus, the correct expression is [tex]\( m - 93 \)[/tex].
Now, let's look at the options provided:
(A) [tex]\( m+93 \)[/tex] - This indicates Rob has 93 more fans than Rose, which is incorrect.
(B) [tex]\( m 93 \)[/tex] - This is not a valid mathematical expression.
(C) [tex]\( 93-m \)[/tex] - This suggests subtracting the number of fans Rose has from 93, which is incorrect.
(D) 93 - This indicates Rob has a fixed number of 93 fans, which is unrelated to Rose's fans.
Therefore, the correct choice is:
[tex]\[ \boxed{m - 93} \][/tex]
This matches option [tex]\( m - 93 \)[/tex], which correctly represents the number of fans Rob has.
