Match the chromosome types based on the position of the centromere as shown in the standard classification:

Column-$I$ (Type)	Column-$II$ (Description)
$1$. Metacentric	$a$. Terminal centromere
$2$. Sub-metacentric	$b$. Sub-terminal centromere
$3$. Acrocentric	$c$. Middle centromere
$4$. Telocentric	$d$. Slightly away from the middle

• A
  $1-c, 2-d, 3-b, 4-a$
• B
  $1-c, 2-d, 3-a, 4-b$
• C
  $1-d, 2-c, 3-b, 4-a$
• D
  $1-a, 2-b, 3-c, 4-d$
