Let \( p, q, r \) be nonzero real numbers that are, respectively, the \( 10^{\text{th}} \), \( 100^{\text{th}} \) and \( 1000^{\text{th}} \) terms of a harmonic progression. Consider the system of linear equations
\( x + y + z = 1 \Rightarrow 10x + 100y + 1000z = 0 \Rightarrow q r x + p r y + p q z = 0 \)

The correct option is:
