Correctly order the steps involved cellular immunity:
1) the tc recognizes the infected host cell
2) the tc interacts with epitope presented by mhc-i on the dendritic cell
3) the tc secretes perforin and granzyme, causing apoptosis
4) the t cell activates the tc cell
a.1,2,4,3
b. 4,2,1,3
c. 2,4,1,3
d. 2,1,3,4

B

Explanation:

The T helper cell needs to acttivate the T cyctotoxic cell in order for the Tc cell to go do its work.

Once the TC cell is active it interacts with MHC-1 proteins on the surface of the infected host cell, this allows the Tc cell to recignise the host cell and begin secreting cytotoxins (perforins and granzymes) in order to degrade the infected cell and cause apoptosis (controlled cell death)
