Which one of the following is the last weapon in the hands of workers:a.lock outb.closurec.striked.layoff

The last weapon in the hands of workers is generally considered to be c. strike.

When workers decide to go on strike, they essentially stop working to protest against their employer's actions or policies, typically in pursuit of better working conditions, wages, or other rights. Strikes can be seen as a last resort after other methods of negotiation and dissent have failed, such as dialogue or bargaining.

The other options—lock out, closure, and layoff—are typically actions taken by management. A lockout refers to an employer's refusal to allow employees to work during a dispute, closure refers to shutting down operations, and layoffs involve firing employees, often for economic reasons. Therefore, a strike is a powerful tool that workers can wield to assert their rights and demands when all else fails.
