Match the parts of sentences given in Column I and Column II to form meaningful and grammatically correct complete sentences.

COLUMN I	COLUMN II
A. Prime Minister Narendra Modi on Thursday attended	D. their three kids for Royal Family's Dinner
B. The Navi Mumbai International Airport began	E. the Christmas service at The Cathedral Church in Delhi
C. Kate Middleton was joined by Prince William and	F. flight operations successfully after a weak's delay

The correct option is A–E, C–D.

To solve this matching problem, let us examine the logical and grammatical connection between the parts in Column I and Column II:

1. Part A with Part E:
Column I: "A. Prime Minister Narendra Modi on Thursday attended"
Column II: "E. the Christmas service at The Cathedral Church in Delhi"
Combining A and E forms a grammatically correct and meaningful sentence: "Prime Minister Narendra Modi on Thursday attended the Christmas service at The Cathedral Church in Delhi." Therefore, A pairs with E.

2. Part C with Part D:
Column I: "C. Kate Middleton was joined by Prince William and"
Column II: "D. their three kids for Royal Family's Dinner"
Combining C and D forms a grammatically correct sentence: "Kate Middleton was joined by Prince William and their three kids for Royal Family's Dinner." Therefore, C pairs with D.

3. Part B with Part F:
Column I: "B. The Navi Mumbai International Airport began"
Column II: "F. flight operations successfully after a weak's delay"
Note that Part F contains a spelling error ("weak's" instead of "week's"), making the combination B–F grammatically incorrect/flawed. Hence, B–F is not included in the correct pairs list.

Thus, the correct valid pairs are A–E and C–D.
