Information utilities and online services: which of the following could a typical information utility (online information service) provide to an end user within the same session? Select the best comprehensive answer.

Introduction / Context:
Online information utilities aggregate diverse databases and live feeds so that a user can retrieve financial data, news, and travel information from one place. The question checks whether you recognize the breadth of content typically offered by such services, especially in enterprise or consumer subscription portals.

Given Data / Assumptions:

• The service integrates multiple information domains (finance, news, travel).
• Users expect near real-time updates for quotes and breaking news.
• Airline schedules are comprehensive for domestic routes.

Concept / Approach:
Information utilities historically bundled feeds like market quotes, wire-service news, and travel timetables. Modern equivalents include financial terminals, online aggregators, and travel metasearch, all using standardized data formats and APIs to present a unified user experience.

Step-by-Step Solution:

Verification / Alternative check:
Look at typical enterprise subscriptions: they include equities/bonds quotes, wire news (e.g., business, politics, markets), and travel data (including airline schedules) under one authenticated platform.

Why Other Options Are Wrong:

Common Pitfalls:
Assuming older utilities handled only one content type; overlooking that licensing allows multiple feeds in one interface.

Final Answer:
All of the above.
