Consider a system consisting of a synchronous generator working at a lagging power factor, a synchronous motor working at an overexcited condition and a directly grid-connected induction generator. Consider capacitive VAr to be a source and inductive VAr to be a sink of reactive power. Which one of the following statements is TRUE?

• A. Synchronous motor and synchronous generator are sources and induction generator is a sink of reactive power.
• B. Synchronous motor and induction generator are sources and synchronous generator is a sink of reactive power.
• C. Synchronous motor is a source and induction generator and synchronous generator are sinks of reactive power.
• D. All are sources of reactive power.
