Answer: The correct option is (A) 6.

Step-by-step explanation: We are given to select the value of x for which the following rational expression become undefined :

E=(3x-5)/(x-6)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

We know that

a rational expression become undefined when the denominator is equal to zero.

Therefore, the rational expression (i) will become undefined when

$x-6=0\\\\\Rightarrow x=6.$

Thus, the required value of x for which the given rational expression become undefined is 6.

Option (A) is CORRECT.
