B. Both processes form woven bone.
Explanation:
Bone growth and development is mainly characterized by bone ossification processes taking place through the two main osteogenic pathways – intramembranous and endochondral ossification.
The woven bones are the primary immature bones formed by both these ossification processes from the bone cells (osteoclasts, osteocytes, osteoblast) and calcified bone matrix. These woven cells later developed into the mature secondary bones or the lamellar bones – spongy (cancellous) or compact (dense cortical) bones.
Intramembranous ossification takes place mesenchymal sheets of connective tissues and produces soft spongy bones.
Endochondral ossification results in replacement of hyaline cartilage to form the long bones.

The right answer is 5 - 10 seconds.
The heartbeat check according to ACLS should not take more than that.
The steps for checking your heartbeat are:
Have a watch. It will be used to measure your heart rate.Choose a place to take your pulse. It is better to choose either the neck or the wrist.
Place your fingers so that you feel your heartbeat. Choose a duration for the measurement (5 to 10 seconds).
Start counting.
Multiply the number by 12 if you counted for 5 seconds (by 6 if it is 10 seconds).
The normal frequency is between 50 and 80 bpm

A nail may be considered as an achiral object because it can
be superimposed when it is faced in a mirror image where in it may look exactly
the same rather than chiral when they are in a mirror image, it wouldn’t be
superimposable.
