A is always paired with T, and C is always paired with G
Therefore ; A - - - - T
C - - - - G
So, TCA replace with their pair (T) A,(C)G, (A)T= AGT. That's it ✅

The correct answer is D. AGT.

Here's why:

- T (thymine) pairs with A (adenine)
- C (cytosine) pairs with G (guanine)
- A (adenine) pairs with T (thymine)

So, if the original DNA strand has the sequence TCA, the complementary strand must have the sequence AGT.

Here's the breakdown:

- T (original) pairs with A (complementary)
- C (original) pairs with G (complementary)
- A (original) pairs with T (complementary)

Therefore, the correct complementary strand is AGT.
