Option B) Lighter - This option is correct because WMLScript is a lighter version of the JavaScript language. It is designed to be used in resource-constrained environments, such as mobile devices with limited processing power and memory.

Option C) Stronger - This option is incorrect because WMLScript is not considered a stronger version of the JavaScript language. Both languages have their own strengths and weaknesses, but WMLScript is specifically optimized for mobile devices.

Option D) Not a version of the JavaScript language - This option is incorrect because WMLScript is indeed a version of the JavaScript language. However, it is a lighter version specifically designed for mobile devices.

The correct answer is B) Lighter. This option is correct because WMLScript is a lighter version of the JavaScript language, specifically designed for mobile devices.
