The statement is incorrect.
Electric charge is quantised, which means the charge on a body can exist only as an integral multiple of the elementary charge (e).
q = ±ne
where (n = 1, 2, 3, ……)
So, a body can have charge like (+e), (-2e), (+3e), etc., but not (1.5e), because 1.5 is not an integer.
Hence, a charge of (1.5e) is not possible on a body.
