Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
EDTA has six sites to donate electrons. hence, it is a hexadentate ligand. It binds twice at the nitrogens and four at the oxygens.
Denticity of a ligand is a number of the lone pairs donated to central atom by ligand. Many ligands are capable of binding metal ions through multiple sites, usually because the ligands have lone pairs on more than one atom.
