Examine the Lewis structure shown above for a particular molecule. Lone pairs (nonbonding pairs) have not been shown.

Of the choices given, which of the following CORRECTLY identifies the measurement of angles (a), (b), and (c), identified below as $\angle (a)$, $\angle (b)$, and $\angle (c)$?

Note that no attempt has been made to try to represent the actual bond angles.

A

$\angle (a)=109.5º$
$\angle (b)=120º$
$\angle (c) = 180º$

B

$\angle (a)=109.5º$
$\angle (b)=120º$
$\angle (c) = 120º$

C

$\angle (a)=120º$
$\angle (b)=120º$
$\angle (c) = 109. 5º$

D

$\angle (a)=180º$
$\angle (b)=90º$
$\angle (c) = 180º$
