Correct option is D
The correct option to fill in the blank is (d)
in a pattern.
Explanation: With the noun
pattern, the natural collocation after verbs like arrange/organize/lay out is
“in a pattern”, meaning “in a particular design/order.” (Hindi: pattern =
नमूना/रूपरेखा/प्रतिरूप). We say “arranged
in rows/lines/circles,” likewise “arranged
in a pattern.”
Example: The tiles were laid
in a pattern to create a mosaic effect.
Explain why other options are incorrect.
•
by a pattern — suggests agency/instrument (“done by X”), which is unnatural here.
•
of a pattern — “of” indicates possession/type (“the pattern
of stripes”), not arrangement.
•
with a pattern — describes possession (a dress
with a pattern), not the act of arranging items.
