Final answer:
The correct shape with 3 bonding pairs, 1 lone pair, and approximately 107° angles is trigonal pyramidal, which is a tetrahedral geometry with one vertex replaced by a lone pair.
Step-by-step explanation:
The shape that has 3 bonding pairs, 1 lone pair, and bond angles of approximately 107° is the trigonal pyramidal geometry. This molecular geometry is similar to a tetrahedral arrangement but with one vertex missing, which is where the lone pair is located. In a tetrahedral arrangement, the bond angles are 109.5°; however, the presence of a lone pair in the trigonal pyramidal shape increases the electron pair repulsion which slightly reduces the bond angles from the ideal tetrahedral angle to about 107°. Therefore, the correct answer is option c) Trigonal pyramidal.
