Answer 2

1) A is correct, R is correct, R is correct explanation of A

• The hybridization of Nitrogen in NH3 is sp3 as three of the hybrids are used to form bonds to hydrogen and the fourth contains the lone pair. The bond angle is found to be 107 degrees. Hence, the given assertion is correct.
• NH3 molecule has a trigonal pyramidal shape. It is only due to lone pair and bond pair repulsion why NH3 molecule has an angle of 107 degrees. If there had been a bond pair, it would have a tetrahedral shape and the angle would have been 109.5 degrees. So, the reason is correct.
• Hence, A is correct, R is correct and R is correct explanation of A.
