If the bottom strand of the DNA is the template, the tRNA anticodon sequence, left to right 5' to 3', for the first RNA codon is:

The DNA strand is read in the 3' to 5' direction, so the RNA strand will be synthesized in the 5' to 3' direction. The tRNA anticodon sequence must be complementary to the mRNA codon sequence, so the codon sequence can be inferred from the anticodon sequence. The anticodon sequence is 5F1F1F1S1F1F1F10 to 3F1F1F1S1F1F1F10. In the 5' to 3' direction, the codon is thus CCC, which codes for proline (P). The best choice is therefore E, CCU, which is the tRNA anticodon for proline.
