To function, i.e. conduct, a junction diode made of silicon requires a forward bias of at least
- 0.2v
- 1.41v
- 1v
Explanation
A silicon junction needs a forward voltage above its turn-on knee of roughly 0.6 to 0.7 V before it conducts properly, so of the values offered only about 1 V is sufficient. The 0.2 V figure corresponds to germanium and is too low for silicon to conduct.

0.7 correct answer, so 1v is the nearest
