Crossing over involves

Crossing over occurs during

Exchange of chromosome segment between maternal and paternal chromatids during meiosis is called

During prophase-I homologous chromosomes pair with each other to form bivalents. Each bivalent is an association of
$a)$ Two chromatids and one centromere
$b)$ Two chromatids and two centromeres
$c)$ Four chromatids and four centromeres
$d)$ four chromatids and two centromeres

The result of crossing over in meiosis
