Which of the following statements are true?
(A) Internet of Things (IoT) wearables are useful for workers employed in hazards conditions. (B) SMTP stands for Simple Mail Transfer Policy. (C) IoT wearables enable people to better understand their own health and allow physicians to remotely monitor them. (D) RAM is non-volatile memory.
Choose the correct answer from the options given below:

Correct option is A

IoT wearables are beneficial for monitoring health and hazardous workplaces. However, SMTP stands for Simple Mail Transfer Protocol, not policy, and RAM is volatile, not non-volatile memory.
Information Booster:
1. IoT Wearables:
· Track health metrics and enable remote monitoring by healthcare professionals.
· Improve safety in hazardous conditions like mining or construction.
2. Volatile vs. Non-Volatile Memory:
· RAM loses data when power is off (volatile).
· Non-volatile memory retains data (e.g., ROM, SSD).
Additional Knowledge:
· SMTP is a standard protocol for email transmission.
· IoT revolutionizes personal health and industrial safety.
