A pair of solution bears the same osmotic pressure. What is this pair

1.	A pair of solution bears the same osmotic pressure. What is this pair of solutions called?(a) Hypertonic(b) Hypotonic(c) Isotonic(d) OsmolarityI have been asked this question at a job interview.My question is taken from Colligative Properties and Determination of Molar Mass in chapter Solutions of Chemistry – Class 12
Answer» RIGHT OPTION is (c) Isotonic To explain I would say: Two solutions having the same osmotic pressure at a given temperature are called isotonic solutions. HYPERTONIC solutions are those in which the concentration of solute outside the membrane and a lesser concentration within the membrane. Osmolarity is a type of concentration expressed in number of solute particles per LITER.
