SSC MTS 2 Aug 2019 Shift 2 Paper

Correct option: 3) hung - this is the most appropriate option.
We cannot use 'hanged' and 'had hanged' because it won't fit as per the context of the sentence.
In situations where someone is given a death sentence, we use 'hanged'.
Hang(V${}_1$) Hung(V${}_2$) Hung(V${}_3$) means to attach or place something so that it is held up without support from below.
Hang(V${}_1$) Hanged(V${}_2$) Hanged(V${}_3$) means to die by being suspended by the neck.
'Hang' is incorrect because 'he' is singular so it must be followed with singular verb hangs which is not present in the given options.
Hence, Option 3 is the most suitable answer.
