When interpreting an attitude indicator for a descent setting, you correlate airspeed, flap setting, and desired descent rate to an approximate pitch attitude.

Option A: The display shows the aircraft symbol positioned with a horizon line configuration that indicates a shallower pitch (closer to level or slight nose-up visually). If your target is a descent at 500 fpm with flaps 10 and 100 kt, this pitch would generally be more nose-down than what is shown here. Therefore, this image is not representative of the specified descent parameters.

Option B: The display shows the airplane symbol significantly below the horizon line, indicating a definite nose-down attitude. At 100 kt with flaps 10 and a descent rate of 500 fpm, you would be pitched nose-down to achieve that rate, and this configuration matches the expected attitude for a controlled descent in that regime. The horizon is lowered relative to the nose, and the small airplane cue sits in a position that corresponds to a descent angle rather than a level flight attitude.

In sum, the correct pitch for a 500 fpm descent at 100 kt with flaps 10 is a moderate nose-down attitude, which aligns with the image in option B. The other image (A) depicts a less steep or near-level pitch, which is inconsistent with the specified descent profile.
