b.) a sudden drop in LDL levels

c.) thinning of the blood

d.) blood clot formation in the swollen area

e.) eating a fatty meal

Answer 1

Answer

Option D is correct i.e " Blood clot formation in the swollen area".

Explanation

Normally, blood clots do not form in the normal arteries. However, blood clot forms if there is some Atheroma (i.e fatty patches or plaques) forms within the lining of arteries. Each plaque has outersell with a soft inner fatty core. If some cracks develop in the outershell of plaque it causes the rupturing of plaque and this rupturing exposes the soft inner fatty core of plaque to the blood which triggers the blood clotting mechanisms that finally results in blood clot formation.
