Suppose You Are Sitting at the Origin of an Inertial $E$

Suppose you are sitting at the origin of an inertial reference frame. You see (that is, you receive the light from) an event $E$ occurring near a clock at $x=-30 \mathrm{~ns}$ at a time $t=80 \mathrm{~ns}$ . When do you observe that event to occur?

A) $\mathrm{t}_{\mathrm{E}}=0$
B) $t_{E}=30 n s$
C) $\mathrm{t}_{\mathrm{E}}=\mathbf{5 0} \mathrm{ns}$
D) $t_{E}=80 n s$ , of course
E) $\mathrm{t}_{\mathrm{E}}=110 \mathrm{~ns}$
F) Some other time (specify)
