Explanation:

Please see the attached image

Given -

Allele for small pollen is "sp"

Allele for normal pollen is "sp+"

and "sp+" is dominant over "sp"

Allele for zebra necrotic tissue is "zn"

Allele for normal necrotic tissue is "zn+"

The gametes of the parent cells are -

sp+ zn+, sp+zn, spzn+, spzn

The cross would be as follows

sp+ zn+ sp+zn spzn+ spzn

sp+ zn+ sp+ sp+ zn+ zn+sp+ sp+ zn+ znsp+ sp zn+ zn+ sp+ spzn+ zn

sp+zn sp+ sp+ zn+ znsp+ sp+ zn znsp+ sp zn+ zn sp+ sp zn zn

spzn+ sp+ sp zn+ zn+sp+ sp zn+ znsp sp zn+ zn+ sp sp zn+ zn

spzn sp+ sp zn+ zn sp+ sp zn zn sp sp zn+ zn sp sp zn zn

Hence, option B is correct
