Dictionary Order Arrangement

To arrange the words in English dictionary order, we compare them letter by letter.

Step 1: Compare Initial Letters

• All words start with 'P'.
• The second letter for all words is 'i'.

Step 2: Compare Third Letter

• The third letters are 'g' (Pigment) and 'l' (Pile, Pilgrim, Pillow).
• Since 'g' comes before 'l' in the alphabet, Pigment comes first.

Step 3: Compare Remaining Words

• We now need to order Pile, Pilgrim, and Pillow.
• Compare the fourth letter: 'e' (Pile), 'g' (Pilgrim), 'l' (Pillow).
• Alphabetical order is e < g < l.
• Therefore, the order is Pile, then Pilgrim, then Pillow.

Step 4: Final Sequence

Combining the results, the correct dictionary order is:

Pigment $\rightarrow$ Pile $\rightarrow$ Pilgrim $\rightarrow$ Pillow

This matches Option B.
