Q290

Consider the system \[ dxdt = Ax + Bu\] with \[A = [ array*20c 1&0\\ 0&1 array ]\] and \[B = [ arrayl p\\ q array ]\] where p and q are arbitrary real numbers. Which of the following statements about the controllability of the system is true?

Consider the system   with A = \left[ {\begin{array}{*{20}{c}} 1&0\\ 0&1 \end{array}} \right]   and  where p and q are arbitrary real numbers. Which of the following statements about the controllability of the system is true?
A.
The system is completely state controllable for any nonzero values of p and q
B.
Only p = 0 and q = 0 result in controllability
C.
The system is uncontrollable for all values of p and q
