Solution

The correct option is A $Z e r o$
$\begin{matrix} I n t h e f o l l o w i n g f i g u r e sin c e, ∣ ∣ ∣ - \to F_{A} ∣ ∣ ∣ = ∣ ∣ ∣ - \to F_{B} ∣ ∣ ∣ = ∣ ∣ ∣ - \to F_{C} ∣ ∣ ∣ a n d t h e y a r e i n c l i n e d w i t h e a c h o t h e r, S o t h e i r r e s u l tan t w i l l b e z e r o . \end{matrix}$
Hence,
option $(A)$ is correct answer.
