Explanation

A. Dry and scaling skin may occur as a side effect of topical corticosteroids, but thinning of the skin is a more concerning adverse effect.
B. While systemic corticosteroids can exacerbate asthma, topical corticosteroids are less likely to worsen asthma symptoms unless used excessively on the face or in high quantities.
C. Reddish-brown discoloration of the skin (hyperpigmentation) is a potential adverse effect of topical corticosteroids but is less common compared to skin thinning.
D. Thinning of the skin (skin atrophy) is a common adverse effect of high-potency topical corticosteroids, especially with prolonged use. This is of particular concern for David given his asthma history, as it may increase the risk of systemic absorption.

C. Passive immunity is effective in preventing or reducing the severity of infections, but it does not last long and does not confer memory or protection against future exposures.
D. Passive immunity acquired through immunoglobulin injection is temporary and wanes over time.
E. Immunoglobulin injection provides passive immunity and is not conferred through vaccination, which induces active immunity.
