Consider the following statements :
Every red is blue. Every blue is green. Every green is yellow.

Which of the following statements denoted by P, Q and R are correct?
P. Every blue is yellow.
Q. Every red is green.
R. Every red is yellow.

Select the answer using the code given below.

Correct Option: (d) P, Q and R

Given statements: 1) Every red is blue (Red is a subset of Blue). 2) Every blue is green (Blue is a subset of Green). 3) Every green is yellow (Green is a subset of Yellow). By syllogism and transitive property: Red -> Blue -> Green -> Yellow. Therefore: P. Every blue is yellow (Since Blue is inside Green and Green is inside Yellow, every blue is yellow is TRUE). Q. Every red is green (Since Red is inside Blue and Blue is inside Green, every red is green is TRUE). R. Every red is yellow (Since Red is inside Blue, Green, and Yellow, every red is yellow is TRUE). Thus, P, Q, and R are all correct. Option (d) is the correct answer.
