Which option represents the correct order of the given words as they would appear in an English dictionary?

1. Measurement

2. Methodology

3. Merchandise

4. Meaningless

5. Memorabilia

Start with the first letters: all begin with M, so check the second letters.

Second letter for all is e— same, check third letters.

Measurement: a (M-e-a)

Methodology: t (M-e-t)

Merchandise: r (M-e-r)

Meaningless: a (M-e-a)

Memorabilia: m (M-e-m)

Now, order by third letter: a < m < r < t

So the words with a as third letter come first:

Measurement (Mea)

Meaningless (Mea)

Between these two, look at fourth letter:

Measurement: s (M-e-a-s)

Meaningless: n (M-e-a-n)

Since n < s, Meaningless comes before Measurement.

So far:
4. Meaningless

1. Measurement

Next comes Memorabilia (Mem), since m comes after a but before r:
5. Memorabilia

Then Merchandise (Mer): r comes after m
3. Merchandise

Finally Methodology (Met): t comes last
2. Methodology

Final order:4, 1, 5, 3, 2

Thus, correct option is (a).
