Step 1:
: Determine the electron geometry of a water molecule.

The water molecule has 2 hydrogen atoms and 1 oxygen atom, which gives it a total of 2 + 2 = 4 electron groups around the central oxygen atom (2 from bonding electrons and 2 from lone pairs). The electron geometry for 4 electron groups is tetrahedral.

Step 2:
: Determine the molecular geometry of a water molecule.

The water molecule has 2 bonding electron groups (to the hydrogen atoms) and 2 lone pairs of electrons. The molecular geometry for 2 bonding electron groups and 2 lone pairs is bent or V-shaped.

Step 3:
: Compare the options provided in the question.

The given options are: a) tetrahedral, tetrahedral b) trigonal planar, trigonal planar c) tetrahedral, bent d) trigonal planar, bent

Step 4:
: Select the correct answer based on the findings from Steps 1 and 2.

The electron geometry of a water molecule is tetrahedral, and the molecular geometry is bent. Therefore, the correct answer is option (c): tetrahedral, bent.

Final Answer

Therefore, the correct answer is option (c): tetrahedral, bent.
