The correct answer is **TATA box**.

### Explanation:
1. **TATA box**: This is a conserved DNA sequence that is typically found about 25-30 base pairs upstream of the transcription start site of eukaryotic genes. It plays a critical role in the formation of the transcription initiation complex by serving as a binding site for transcription factors and RNA polymerase.

2. **Codon**: This refers to a sequence of three nucleotides that corresponds to an amino acid or a stop signal during protein synthesis, but it is not specifically involved in the formation of the transcription initiation complex in promoters.

3. **Start point**: While this is related to where transcription begins, it's not a specific component of the promoter that is crucial in the formation of the initiation complex.

4. **Exon**: Exons are the coding regions of a gene that are expressed, but they are not part of the promoter region.

Therefore, the most relevant choice that directly contributes to the transcription initiation complex formation in eukaryotes is the **TATA box**.
