rb 13 14 15 16
the offspring in the box labeled 6 would be...
○ rrbb
● rrbb
○ rrbb
○ rrbb

Explanation:

Box 6 is at the intersection of row "Rb" and column "Rb". To find the genotype, combine the alleles from the row and column: the row contributes R and b, the column contributes R and b. Pairing the corresponding alleles gives RR (from the R alleles) and bb (from the b alleles), so the genotype is RRbb.

Answer:

C. RRbb
