Solution

The correct option is B $130$ points
$∙$ Charlie's overall score for correct answers $= 400$ points
$∙$ Charlie scored due to negative marking towards incorrect answers $= - 270$ points

$∴$ Charlie's net score $=$ Charlie's score for correct answers $+$ Charlie's score for incorrect answers
$= (400 + (- 270))$ points
$= (400 - 270)$ points
$= 130$ points

Hence, Charlie's net score is $130$ points, i.e., option (b.) is the correct one.
