Final answer:
Jasplakinolide treatment in the T. gondii life cycle primarily targets the 2) invasion of host cells. Hence, 2) is correct.
Step-by-step explanation:
The primary target of jasplakinolide treatment in the T. gondii life cycle would be invasion of host cells.
Jasplakinolide is a compound that disrupts the actin cytoskeleton, which is essential for the invasion process of T. gondii.
