All the above options are used as universal indicators of pH in a laboratory.
There are 2 scenarios here.
1. Litmus seems to be the odd one out while classifying the indicators.
Methyl orange and Phenolphthalein are artificial chemical pH indicators, whereas, Litmus is a naturally occurring pH indicator that is extracted from lichens.
2. However, if the color of solutions is considered, then Phenolphthalein is the odd one out.
Litmus and methyl orange show red color for low pH acidic solutions, whereas Phenolphthalein is colorless in acidic solutions.

Hey there!
Given Options ->
1.litmus
2.methyl orange
3.phenolphthalein
4.universal indicator
We see that all share a common propery that they are indicators. But the Odd one is Universal indicator.
Litmus paper turns blue or red to show that they are basic or acidic . Methyl orange also turns yellow or red to indicate acidic nature and basic nature . Phenopthalein turns pink, or colourless to indicate acidic and basic natures.
So, It is evident that Litmus, Methyl orange, Phenopthalein share a common property that they can change colors to indicate the nature of the substance either basic or acidic or neutral.
But Universal indicator can turn to different colors at different ranges of PH which makes it a go to indicator for all things.
Hence, Odd one out is Universal indicator.
