Subject: The sentence starts with R (she) because it is the subject performing the action.
Starting point: She
Verb: Next, we need the action word, which is P (baked).
Progress: She baked
Object Determiner: The article Q (a) comes next to introduce what was baked.
Progress: She baked a
Adjective: The word O (delicious) describes the object and logically follows the article.
Progress: She baked a delicious
Object: Finally, we add the object S (chocolate cake) to complete the sentence.
Complete Sentence: "She baked a delicious chocolate cake."
Thus, the correct sequence is RPQOS.
