Solution

The correct option is A Four homologous chromosomes with four chromatids
Tetrads are formed in prophase I of meiosis I. Tetrad consist of two homologous chromosomes, each with two chromatids. Thus, a tetrad consists of 4 chromatids, two of which belong to each chromosome called sister chromatids which are joined at the centromere.
