Three ammeters \( A, B \) and \( C \) of resistances \( R_{A}, R_{B} \) and \( R_{C} \) respectively are joined as shown. When some potential difference is applied across the terminals \( T_{1} \) and \( T_{2} \), their readings are \( I_{A}, I_{B} \) and \( I_{C} \) respectively. Then,
(a) \( I_{A}=I_{B} \)
(b) \( I_{A} R_{A}+I_{B} R_{B}=I_{C} R_{C} \)
(c) \( \frac{I_{A}}{I_{C}}=\frac{R_{C}}{R_{A}} \)
(d) \( \frac{I_{B}}{I_{C}}=\frac{R_{C}}{R_{A}+R_{B}} \)
