Select the option that represents the correct order of the given words as they would appear in an English dictionary.
1. Phantom
2. Photograph
3.Philosophy
4. Physical
5. Pharynx
6. Physics

All six words begin with the same two letters “Ph”. Hence we compare them from the 3rd letter onward, just as a dictionary does.

3rd letter check:
Phantom     → a
Photograph  → o
Philosophy   → i
Physical      → y
Pharynx     → a
Physics      → y

The alphabetical order of these 3rd letters is: a < i < o < y. Therefore, the two words starting with “Pha-” come first, followed by the single “Phi-” word, then the single “Pho-” word, and finally the two “Phy-” words.

Compare letter by letter:
P h a n … (Phantom)
P h a r … (Pharynx)
Since n < r, Phantom comes before Pharynx.

Only Philosophy is present, so it stays where it is.

Only Photograph is present, so it stays where it is.

Both share the block “Physi”. Compare the next different letter:

Physica… (Physical)
Physics… (Physics)
After “c”, Physical has “a” while Physics has “s”. Since a < s, Physical comes before Physics.

Combining all cases, the complete dictionary order is:
1. Phantom (1)
2. Pharynx (5)
3. Philosophy (3)
4. Photograph (2)
5. Physical (4)
6. Physics (6)

Thus the correct sequence is 1, 5, 3, 2, 4, 6.

Option C which is: 1, 5, 3, 2, 4, 6
