The correct option is
C And
Option B: 'And' is a conjunction that connects phrases, clauses or words. It means 'in addition to'. It is relevant to the given sentence, connecting the words 'locks' and 'chains'. Hence option B is correct.
Option A: 'With' means 'accompanied by'. 'With' is not a connecting word, and will not form a complete meaning here.
Option C: 'For' expresses purpose.
Option D: 'In' means 'inclusion within a space'.
These words do not relate to the given sentence in meaning.
Hence options A, C and D are incorrect.
