Concept:
The Speaker of the Lok Sabha is the presiding officer of the lower house of Parliament of India. Each Lok Sabha term corresponds to a specific Speaker elected by the members of the house. Correct matching requires knowledge of parliamentary chronology.
Step 1: XIth Lok Sabha (1996–1997)
The XI Lok Sabha saw a fragmented coalition era.
P. A. Sangma was elected as Speaker, becoming one of the prominent leaders from the North-East to hold this constitutional post.
\[
(a) \rightarrow (IV)
\]
Step 2: XIVth Lok Sabha (2004–2009)
During the UPA-1 government,
Somnath Chatterjee served as the Speaker and presided over parliamentary proceedings.
\[
(b) \rightarrow (III)
\]
Step 3: XVth Lok Sabha (2009–2014)
Meira Kumar became the first woman Speaker of the Lok Sabha, marking a historic milestone in Indian parliamentary history.
\[
(c) \rightarrow (II)
\]
Step 4: XVIth Lok Sabha (2014–2019)
Sumitra Mahajan served as Speaker, becoming the second woman to hold this position.
\[
(d) \rightarrow (I)
\]
Step 5: Final Matching
\[
a-IV,\quad b-III,\quad c-II,\quad d-I
\]
Thus, Option B is correct.
