Answer: First option is correct.

Step-by-step explanation:

Since we have given that

Complex number is the number which contains real number along with imaginary number in the form of a+bi.

It is shown by "Argand plane" in which x-axis represents real number and y-axis represents imaginary number .

Hence, according to option,

4+3i is the only complex number as it has one real number a = 4 and one complex number b =3.

Hence, First option is correct.
