Splice sites are directional in nature. 5’ splice site -the left, or donor, site and the 3’ splice site - right, or acceptor, site. So, in below table the complex and their events are given match them correctly .

Column 1	Column 2
1. E complex	a. Joining of U4/6 and U5 tri-snRNPs
2. A complex	b. U2 addition to base pair with the branch site in the presence of ATP
3. B1 complex	c. Formation of commitment complex in which U1 is base paired with the 5' splice site
