hi rakhi,

i checked dutta pg no 88--it says .....posterior fontanelle floor is membranous and b'comes bony before term.......

well checked BDC Anatomy ---pg 309(head neck brain)says anterior fontanelle closes -18 months
................posterior and sphenoid fontanelle-b/w 2nd and 3rd month of life...........mastoid fontanelle by 12 months:?

doesn't fit in any of ur options

but yes one more thing i found BDC pg 7 ........says the posterolateral fontanelle closes by the end of frst year.....

searched web everywhere its given around two months...........none of the options match...

but if i consider that u mentioned" fonatanelles" and not just fontanelle.......then considering the closure of posterolateral fontanelle as well ......i assume the answer to b option 1
