Correct answer: B. XY
- A. XX
- B. XY
- C. XO

Explanation
In butterflies, females typically have a ZW sex-determination system, where females are ZW and males are ZZ. This is different from the XY system found in many mammals. So, in terms of chromosomes, female butterflies have one Z chromosome and one W chromosome.

About X-linked Recessive Inheritance
X-linked recessive inheritance involves genes on the X chromosome, so males express a recessive allele with no corresponding allele on their single X chromosome, while females may be carriers. Pedigrees cover haemophilia and red-green colour blindness, including carrier mothers, affected sons and the absence of father-to-son transmission.
