Correct answer: C
Correct Option: C
Explanation: Because OLEDs are self-emissive organic thin-film devices, they can be fabricated on flexible substrates, integrated into wearable/roll-up designs, and constructed as transparent displays.
Statement/Pair-wise Analysis:
Statement/Item 1: Correct - OLED thin films can be deposited on suitably engineered flexible plastic substrates.
Statement/Item 2: Correct - Flexible OLED sheets can be used in bendable or rollable displays and smart fabrics.
Statement/Item 3: Correct - Transparent OLED display architectures are technically possible.
Option-wise Analysis:
A: Incorrect - omits correct statement/item 2.
B: Incorrect - omits correct statement/items 1, 3.
C: Correct - includes all and only the true statements/items.
D: Incorrect - omits correct statement/items 1, 2, 3.
