RNA is synthesized complementary to the DNA template strand. Use base-pairing rules for transcription: DNA A → RNA U, DNA T → RNA A, DNA C → RNA G, DNA G → RNA C. Applying these rules to each triplet of the given template yields the mRNA sequence.

Given template (grouped in codons): 
TAC  CGC  TGC  TTC  CGG  CAC  ACG  CAC

Transcription codon-by-codon (showing each base conversion):
- TAC → T→A, A→U, C→G  → AUG  
- CGC → C→G, G→C, C→G  → GCG  
- TGC → T→A, G→C, C→G  → ACG  
- TTC → T→A, T→A, C→G  → AAG  
- CGG → C→G, G→C, G→C  → GCC  
- CAC → C→G, A→U, C→G  → GUG  
- ACG → A→U, C→G, G→C  → UGC  
- CAC → C→G, A→U, C→G  → GUG

Concatenating the transcribed codons in the same order gives the full mRNA sequence:
AUG GCG ACG AAG GCC GUG UGC GUG

Why this is correct: each mRNA base is the complement of the corresponding base on the DNA template following the transcription rules; the first codon AUG is also the canonical start codon (methionine), consistent with a coding region. No alternative sequences are correct because any deviation would violate base-pairing (for example, writing U for a DNA T would be incorrect — DNA T pairs with RNA A, not U).

Conclusion: The transcribed mRNA sequence is AUG GCG ACG AAG GCC GUG UGC GUG, which matches the provided correct answer.
