Knitting is interlooping of yarn . You may have seen your grandmother making an sweater with the help of needles.That process is known as knitting .Here the fabric is manufactured with the help of the loops.
Hence option A is correct.

Spinning is the process of making yarn from fiber.

Weaving is primarily done by interlacing two orthogonal sets (warp and weft) of yarns in a regular and recurring pattern.
Hence option C is correct.

In knitting, a single yarn is used to make a piece of fabric.

The ginning of cotton is the process of separation of fibres from the seeds by combing.
From the bolls, cotton is usually picked by hand. Fibres are then separated from the seeds by combing. This process is called ginning of cotton.

After harvesting the cotton seeds with cotton balls form the crop. The seeds are removed from cotton. This process is called ginning.

Warp Yarn is that kind of yarn from which we can get multiple ends of yarn from a given package. While the wept yarn is that in which we have a single end . The end means thread-like thing. ie from a package of warp we can unwind multiple threads at a time while not in case of wept.

True, 

The unseede cotton fibre got from the ginning process is subjected to spinning process to make it as yarn.The process of formation of yarn from the unseeded cotton fibre is called as spinning.
Hence option A is correct.

 The Born-Haber Cycle can be applied to determine the lattice energy of an ionic solid; ionization energy, electron affinity, dissociation energy, sublimation energy, heat of formation, and Hess's Law.
