Hint: Think about the colours and properties of all the options given here and try to narrow down the possibilities using the more common lead compounds as reference.

- $P{{b}_{3}}{{O}_{4}}$
- $PbO$
-$Pb{{O}_{2}}$
- $P{{b}_{4}}{{O}_{3}}$
From all this information, we can deduce that the only compound that has a purely red colour is the lead tetraoxide. So, the answer to this question is ‘A. $P{{b}_{3}}{{O}_{4}}$’.
