Question about Lighting Calculations

appropriate. Let $M$ be the object$-$to$-$world transform, $V$ be the world$-$to$-$view transform, and $P$ be the view$-$to$-$CCS transform.

Which sets of transformed point, normal, light direction, and eye position below can be used together to compute the Phong illumination at the point? Select all that apply.

$M{p}_{\text{o}\text{c}\text{s}},M{n}_{\text{o}\text{c}\text{s}},l_{wcs},e_{wcs}$

$M{p}_{\text{o}\text{c}\text{s}},M{n}_{\text{o}\text{c}\text{s}},M{l}_{wcs},M{e}_{wcs}$

$VM{p}_{\text{o}\text{c}\text{s}},VM{n}_{\text{o}\text{c}\text{s}},V{l}_{wcs}(e_{wcs}$ is not available$)$

$PVM{p}_{\text{o}\text{c}\text{s}},PVM{n}_{\text{o}\text{c}\text{s}},PV{l}_{wcs},PV{e}_{wcs},($all followed by division by the fourth coordinate$)$
