Final Answer:
The correct spelling of the word is 2) physiologic.
Step-by-step explanation:
The correct spelling of the word is "physiologic" (Option 2). The key to identifying the correct spelling lies in the root word "physio," which relates to the functions and processes of living organisms. The option "physiologic" correctly maintains the order of the letters in the root word, including the correct placement of the letters "i" and "o."
Option 1) "psysiologic" contains an additional "s" and swaps the positions of "i" and "y," resulting in an incorrect spelling that deviates from the standard structure of the word.
Option 3) "phsiologic" also contains a misplaced "i" and lacks the correct sequence, making it an incorrect spelling.
In summary, the correct spelling, "physiologic," aligns with the established conventions of English spelling and maintains the accurate arrangement of letters based on the root word, ensuring clarity and correctness in written communication.
