t-distribution is a family of continuous probability distribution which arise when finding mean of normally distributed population. Observing the given figure, select the correct statement :

Mean of t-distribution lie between -∞ to ∞. As the number of degree of freedom decreases; the t-distribution curve moves closer to standard normal distribution curve. B-denotes standard normal distribution. If degree of freedom is infinite, then t-distribution curve and normal distribution curve are exactly the same

If degree of freedom is infinite, then t-distribution curve and normal distribution curve are exactly the same
