Choose the correct statements with respect to above synthetic sequence. [$p^{k_1},p^{k_2}\&p^{k_3}$  of $"F"$  respectively, are 1.88, 3.65, 9.67]

Compound “F” is aspartic acid

P^I of "F" is in the acidic range of P^H scale

At P^H= 1.5, “F” exists as conjugate acid

At P^H= 2.765, net charge on “F” is zero.
