The disadvantages of TIG welding are:

• The need for a continuous gas flow. TIG welding uses a shielding gas to protect the weld from oxidation. This gas must be supplied continuously, which can be inconvenient and expensive.
• Specialized labor. TIG welding is a skilled process that requires a trained welder. This can make it more expensive than other welding methods.
• Slower welding speed. TIG welding is a slower process than other welding methods, such as MIG welding. This can make it less productive for some applications.

So the answer is (a), the need for a continuous gas flow and specialized labor.

The other options are incorrect. TIG welding does not typically produce lower cost of production or simpler welding processes. TIG welding can produce stronger and more ductile welds, and it can produce less deformation near the weld bead. However, these are not disadvantages of the process.
