Q. Which one is false?

Glucose and galactose can act as inducers for lac operon.

The presence of introns in split gene is reminiscent of antiquity and the process of splicing represents the dominance of RNA-world.

In eukaryotes - DNA $\to$ hnRNA $\to$ mRNA.

Regulation of lac operon by repressor is referred to as negative regulation. Lac / lactose operon is under control of positive regulation as well.

Correct answer is (a) Glucose and galactose can act as inducers for lac operon.
