The Correct Option is B

Solution and Explanation

Step 1: Theory
Newton's theory proposed light consists of particles called corpuscles.
Step 2: Denser Medium

The theory incorrectly predicted that denser media exert a greater attractive force, making light faster.
Step 3: Conclusion

Consequently, the speed is predicted to be slower (lesser) in a rarer medium compared to a denser one.
