a.

Interpretation Introduction

Interpretation:

The complete structure with all atoms and lone pairs of the given compound has to be drawn.

${{\text{(CH}}_{\text{3}}\text{)}}_{\text{2}}{\text{CHCONH}}_{\text{2}}$

Concept Introduction:

To draw a complete structure, the carbon has to be drawn at the junction of each polygon, add enough hydrogen to the carbon four bonds.  The atom except carbon and hydrogen atom are known as heteroatom.  The lone pairs of electrons present in the heteroatom such as nitrogen, oxygen have to be drawn.  The bond between carbon and hydrogen has to be drawn.
