Solutions: ( 1 to 10 )
1) Answer (b)
When we sequentially fill “cacc” in the gaps we get
a c ca a ca c caa c
When we split the sequence as three parts, we get acca , acac and caac.
The first term and the last term have the same first and last letters while the middle term has alternate letters thus forming a pattern.
Hence Option B is the correct answer.
