. . . . . . . . President and . . . . . . . . S. D. O. is coming.

Solution (By Examveda Team)

In English grammar, the article "the" is used before titles when referring to a specific person holding a particular position.

First blank: "President" is a unique title referring to a specific person, so "the" is used.

Second blank: "S.D.O." (Sub-Divisional Officer) is also a specific designation, so "the" is required.

Thus, the correct sentence is:

The President and the S.D.O. is coming.
