Answer:

B′C′ = 2

Step-by-step explanation:

Recall that reflection is a rigid motion.

The reflected triangle will be congruent to the pre-image.

This means that the corresponding sides will be congruent

We have that: BC of triangle ABC has length 2 units.

This implies that:

B'C' of triangle A'B'C' also has length 2 units.

Therefore the correct answer is B′C′ = 2
