A plane mirror is moving with velocity \( 4 \hat{\mathrm{i}}+5 \hat{\mathrm{j}}+8 \hat{\mathrm{k}} \). A point object in front of the mirror moves with a velocity \( 3 \hat{i}+4 \hat{j}+5 \hat{k} \). Here \( \hat{k} \) is along the normal to the plane mirror and facing towards the object. The
\( \mathrm{P} \) velocity of the image is:
W
(A) \( -3 \hat{i}-4 \hat{j}+5 \hat{k} \)
(B) \( 3 \hat{i}+4 \hat{j}+11 \hat{k} \)
(C) \( -3 \hat{i}-4 \hat{j}+11 \hat{k} \)
(D) \( 7 \hat{\mathrm{i}}+9 \hat{\mathrm{j}}+11 \hat{\mathrm{k}} \)
