• B. Heart $\to$ Artery $\to$ Arteriole $\to$ Capillary $\to$ Vein $\to$ Venule
• C. Heart $\to$ Artery $\to$ Arteriole $\to$ Capillary $\to$ Venule $\to$ Vein

Answer 1

The correct option is C Heart $\to$ Artery $\to$ Arteriole $\to$ Capillary $\to$ Venule $\to$ Vein

Arteries branch to form arterioles and arterioles branch to form capillaries. Tissues exchange substances with blood through capillaries. Capillaries join to form venules which then join to form veins.
