- F.
  
  F
Correct Answer
D. D

Explanation
The correct answer is d. In the given options, only option d is a tetrahedral shape. A tetrahedron is a three-dimensional shape with four triangular faces, six edges, and four vertices. Option d represents a tetrahedron as it has four triangular faces meeting at a common vertex.

  Its called linear triatomic
- E.
  
  This shape says the molecule is polar
Correct Answer(s)
A. Its angle is 180*
C. It involves 3 atoms
D. Its called linear triatomic

Explanation
H2O is a bent triatomic shape, and this shape is NOT polar because the two opposing atoms are canceling one another's polarity out.
