bToggleObj.GetComponent<Toggle>().isOn = false;
cToggleObj.GetComponent<Toggle>().isOn = false;

ToggleGroup toggleGroup = canvasObj.AddComponent<ToggleGroup>();
aToggleObj.GetComponent<Toggle>().group = toggleGroup;
bToggleObj.GetComponent<Toggle>().group = toggleGroup;
cToggleObj.GetComponent<Toggle>().group = toggleGroup;
