Question

$\overrightarrow {PA} + \overrightarrow {PB} = 2\overrightarrow {PC} $

$\overrightarrow {PA} + \overrightarrow {PB} = \overrightarrow {PC} $

$\overrightarrow {PA} + \overrightarrow {PB} = 2\overrightarrow {PC} = \overrightarrow 0 $

$\overrightarrow {PA} + \overrightarrow {PB} = \overrightarrow {PC} = \overrightarrow 0 $
