The answer is B: It is secure and doesn't harm flight characteristics or control

Before flight the remote PIC must ensure that any object attached to or carried by the small UA is secure and does not adversely affect its flight characteristics or controllability. Part 107 doesn't require the manufacturer's written approval for an attachment, and registration doesn't list payloads.

Correct

The answer is A: Difficulty raising the nose to flare

A CG beyond the forward limit makes the aircraft nose-heavy, which can make it difficult or impossible to flare for landing, and it also raises stalling speed and control forces. Light, oversensitive pitch control comes from an aft CG, and a forward CG pushes the nose down, not up.

Correct

The answer is B: 48 knots

√2.923 ≈ 1.710, and 28 kt × 1.710 ≈ 48 knots, a large jump that makes a stall possible at a seemingly safe speed. Multiplying by the load factor (82 knots) overstates it, and 28 knots ignores the steep turn.

Correct

The answer is C: Data that other users of the same make and model have published

Manufacturers' performance information isn't standardized, and when none is published FAA guidance suggests seeking data already determined and published by other users of the same model and using it as a starting point. Manned-aircraft charts don't describe a small UA, and the FAA doesn't publish performance data for registered drone models.

Correct

The answer is A: 5,300 feet

Pressure altitude = 2,500 + (29.92 − 30.12) × 1,000 = 2,300 ft, because a setting above 29.92 lowers it. Standard temperature there is about 10.4 °C, so 35 °C is 24.6 °C above standard: 2,300 + 120 × 24.6 ≈ 5,300 feet. Adding the pressure correction instead of subtracting it gives 5,700 feet, and stopping at pressure altitude gives 2,300 feet. The FAA's handbooks find density altitude with a chart or flight computer; the rules of thumb given in the question approximate that result.
