1:Drilling#manufacturing of a specific diameter hole.

2:Boring#enlarging of the existing hole.

3:Tapping#used for fine finishing of the internal surface of a hole.

4:Spot facing#smooting and squaring of the surface around a hole.

Hence drilling is the correct answer.

Spot facing comes sometimes before and sometimes after drilling and boring only. So not first.

But the next definate process should be drilling because if no drilling how boring will come.

The answer should be drilling.

Because boring & tapping definitely will not be correct. And spot facing used where free hole needed for properly for sitting the head of Allen key bolt.

After Tapping, no further operation. so, the sequence should be;

1) DRILLING
2) BORING
3) SPOT FACING (To fit the front of the tap in the hole easily)
4) TAPPING.

Boring is the correct answer, because all other process are carried out after the drilling, so the sequence is drilling, boring, spot facing and tapping.

Drilling is the correct answer because with out drilling we cannot make boring. So the sequence is:

1) Drilling.
2) Boring.
3) Tapping
4) Spot facing.

Drilling is the correct answer. Also boring is enlarging existing hole and spot facing is done after threading and some how tapping.

Spot facing is the answer. Because between 4 options given we will first do spot facing. Then drilling the boring and then taping.

It must be drilling first. Drilling is originating a hole and boring is enlarging the hole previously drilled in drilling.
