D is the correct answer because in option A. It is given that solder melts above 400 C. Which is correct as it range is (90-450).

I think A is the wrong one.

Brazing is a metal-joining process in which two or more metal items are joined together by melting and flowing a filler metal into the joint.

The correct answer is C.

SOLDER IS A FUSIBLE METAL ALLOY with a melting point (or range) of 90 to 450°C (190 to 840°F) , used in a process called soldering, in which it is melted to join metallic surfaces (which of course must themselves have higher melting temperatures so that they remain solid when the solder is melted). It is especially useful in electronics and plumbing. Alloys that melt between 180 and 190°C (360 and 370°F) are the most commonly used. If alloys with melting points above 450°C (840°F) are used, the process is no longer called soldering but brazing. Solder can contain lead and/or flux, but in many applications, solder is now lead-free.
