Which among the given is the prime concern in cloud computing?*1 pointAccessibilityToo many platformsSecurity concernsToo expensive

The correct choice from the provided options regarding the prime concern in cloud computing is Security concerns.

Explanation:

1. Accessibility: While accessibility is important as it allows users to reach their data and applications from anywhere, it is not typically considered the primary concern when comparing it with security issues.

2. Too many platforms: The variety of platforms can be overwhelming, but it does not directly affect the core functionality or security of cloud computing.

3. Security concerns: This is indeed the most critical concern in cloud computing. With data being stored and processed on third-party servers, issues like data breaches, unauthorized access, and compliance with regulations pose significant risks to users and organizations.

4. Too expensive: Cost considerations are always important, but the primary concern for most organizations is how secure their data is in the cloud, rather than just the expense involved.

In summary, while all the factors mentioned are relevant aspects of cloud computing, security concerns remain the foremost priority due to the potential risks associated with data protection and privacy.
