In level flight with a fractured static line, altimeter reads higher than actual. Which option represents this condition?

Explanation:
The key idea is how a fractured static line affects the pitot–static system. If the static line leaks, the static pressure sensed by the instruments becomes lower than the actual ambient pressure. A lower sensed static pressure makes the airspeed indicator read higher than the true airspeed, because the difference between pitot pressure and static pressure (used to derive IAS) increases. At the same time, the altimeter uses static pressure to indicate altitude, so a lower sensed static pressure makes the altimeter show a higher altitude than actual. Thus both the indicated airspeed and the altimeter overread.
