Assertion (A) Analysis:

• Assertion A states that print material disadvantages include a lack of interaction and audio-visual elements.
• This is accurate. Unlike digital or multimedia resources, traditional print materials are static and cannot inherently provide interactive features or audio-visual components.
• Therefore, Assertion A is true.

Assertion (B) Analysis:

• Assertion B claims print materials are not portable, not easily available, and not cost-effective.
• Portability: Print materials like books and newspapers are generally portable.
• Availability: Print materials are widely available through bookstores, libraries, and other distribution channels.
• Cost-effectiveness: Print materials can be cost-effective, especially compared to the costs associated with digital devices and potential subscription fees.
• Since print materials possess portability, are generally available, and can be cost-effective, the claims in Assertion B are inaccurate.
• Therefore, Assertion B is false.

Conclusion:

• Assertion A is true.
• Assertion B is false.

The correct option is that A is true and B is false.
