The correct complementary DNA strand is 'TGTCAGCTACGT'.

Explicação

## Step 1<br />In DNA, the nucleotide Adenine (A) always pairs with Thymine (T), and Cytosine (C) always pairs with Guanine (G). This is known as the base pairing rule in DNA.<br /><br />## Step 2<br />Given the DNA sequence ACAGTCGATGCA, we need to find the complementary DNA strand. This means we need to replace each A with T, each T with A, each C with G, and each G with C.<br /><br />## Step 3<br />Applying the base pairing rule to the given DNA sequence, we get the complementary DNA strand as TGTCAGCTACGT.
