Given below are two statements. In the light of the above statements, choose the most appropriate answer from the options given below.

Statement I:3D printers are primarily used with CAD.

Statement II:OLEDs require some form of back-lighting so that the screen can be lit up.

ABoth Statement I and Statement II are correct

BBoth Statement I and Statement II are incorrect

CStatement I is correct but Statement II is incorrect ✓ Correct

DStatement I is incorrect but Statement II is correct

Correct answer: (C) Statement I is correct but Statement II is incorrect

Explanation

3D printers work mainly from CAD models, which supply the digital design that guides the layered printing.

Statement 1 correctly links 3D printing with computer aided design as its main input source.

Statement 2 is wrong because OLED screens emit their own light and need no back-lighting.

Back-lighting is required by LCD panels, whose liquid crystals cannot produce light themselves.

This self-emissive property gives OLEDs deeper blacks and thinner displays.

CAD combined with 3D printing supports rapid prototyping across engineering and design.
