Answer 1

The correct option is A Body cells- XX, Sex cells- all X

Option a is the right answer. Each person normally has one pair of sex chromosomes in each cell. Female have two X chromosomes, while male have one X and one Y chromosomes. Reproductive cell i.e. the sex cell contains half the no. of total chromosomes in the organism thus the sex chromosome also halves.
