The process of removing introns from the mRNA in eukaryotes is called
A
Capping
B
splicing
C
Tailing
D
Slicing
Explanation: 

Detailed explanation-1: -Removal of introns and joining the exons in a defined order in a transcription unit is called as splicing. Splicing is a modification of the nascent pre-messenger RNA transcript in which introns are removed and exons are joined.

Detailed explanation-2: -Splicing of precursor mRNAs (pre-mRNA) is an important step during eukaryotic gene expression. The identification of the actual splice sites and the proper removal of introns are essential for the production of the desired mRNA isoforms and their encoded proteins.
