Private carriage in aviation is defined as carriage for hire that does not involve "holding out" to the public. This means that the operator does not publicly advertise or offer their services to the general public as a commercial service would. Instead, private carriage typically involves specific arrangements or contracts with a limited number of clients or entities, often based on personal or business needs.

In contrast to this definition, the other options suggest characteristics typical of public carriage. Option A refers to public advertisement, which is a key aspect of public carriage, as it indicates an offer to transport anyone who is willing to pay the fare. Option C, while touching on corporate transportation, is too narrow and doesn't encompass the broader definition of private carriage—private carriage can include other types of clientele beyond just corporate officials. Finally, option D suggests a criterion based on altitude, which is not relevant to the definition of private carriage at all, as this type of designation relates primarily to the nature of the business arrangement rather than operational parameters such as altitude.

Thus, the clarity in the definition of private carriage lies in the absence of public offering and advertisement, aligning perfectly with the correct answer.
