Select the correct option that indicates the arrangement of the given words in the order in which they appear in an English dictionary.
Possibility

Possession

Posthumous

Posterity

Possessive

Let's arrange the given words letter by letter in alphabetical order:
Possibility

Possession

Posthumous

Posterity

Possessive

All words start with "Poss-" or "Post-". Since 's' comes before 't', words starting with "Poss-" come first.
Let's sort the "Poss-" words:

Possi... (Possibility)

Posse... (Possession, Possessive)

Between "Posse...", let's compare:

Possession (has 's' at 7th position)

Possessive (has 's' at 7th position, then 'i' vs 'i'... wait, let's compare letter by letter):

P-O-S-S-E-S-S-I-O-N (Possession)

P-O-S-S-E-S-S-I-V-E (Possessive)
Up to the 8th letter 'I', they are identical. The 9th letter of Possession is 'O' and Possessive is 'V'. Since 'O' comes before 'V', 2 comes before 5.

Then comes "Possibility" (1) because 'i' comes after 'e'.
So the order for the first three is: 2, 5, 1.

Now let's sort the "Post-" words:
3. Posthumous
4. Posterity

Comparing "Poste..." and "Posth...": since 'e' comes before 'h', 4 comes before 3.

Combining all together, the dictionary order is: 2, 5, 1, 4, 3.
