During transcription two strands of DNA are named differently i.e Template strand and coding strand.

Template strand:

Strand from which RNA is producing is known as template strand while

Coding strand:

The strand which is opposite to the template strand is known as the coding strand. Coding strand is the DNA strand whose nucleotide sequence resembles to the RNA transcript base sequence except thymine which is replaced by uracil.

Correct Answer:

Template strand from 5' to 3' reads GGCTCA. and

In this question CCGAGT is coding strand.

RNA sequence is same as coding sequence except T which is replaced by U so sequence of RNA becomes
