What would be the phenotype of an int- h mutant?
A) The cell would build up high levels of h repressor, so lysogeny would be maintained.
B) The phage would be able to enter the lytic cycle, but would not be able to lysogenize.
C) The phage would be able to lysogenize but would not be able to be induced to resume the lytic cycle.
D) The phage would not be able to undergo the lytic cycle, but could lysogenize.
E) Both lytic and lysogenic pathways would be inactivated.

The int gene is responsible for integrating the phage genome into the host bacterial genome, a crucial step for lysogeny. An int- h mutant would lack this integration function, preventing lysogeny but not affecting the lytic cycle.
