Answer

Correct option: D.
All option are right
We know a prime $x > 6$ can be always written as $6k + 1$ or $6k - 1,$ when $k$ is an integer.
Option $A \rightarrow 889 = 6 \times 148 + 1$
Option $B \rightarrow 997 = 6 \times 166 + 1$
Option $C \rightarrow 899 = 6 \times 133 + 1$
Option $D \rightarrow 1147 = 6 \times 191 + 1$
$\therefore$ All the options are correct.
