Answer:
Option B, 3 : 1
Step-by-step explanation:
It is given that
H - represents the shiny object allele
h - represents the dull object allele
Also H is dominant over h
Now punnet representing the the cross between parents having genotype "Hh" is as follows -
H h
H HH Hh
h Hh hh
Out of four allele, only genotype "hh" represents the phenotype of dull object.
Hence, phenotype ratio is as follows -
Shiny object : dull object
3 : 1
Hence, option B is correct
