Final Answer:
Satement c) is invalid because it attempts to assign multiple values to a single variable using a comma-separated list, which is not a valid syntax in programming.
Explanation:
a) mₙ_q = 3500
This statement is valid. It defines a variable mₙ_q and assigns it the value 3500.
b) m.n.q = 3500, 3600, 3700
This statement is valid. It defines three variables m, n, and q, and assigns them the values 3500, 3600, and 3700, respectively.
c) m,n,q = 3500, 3600, 3700
This statement is invalid because it attempts to assign three values (3500, 3600, 3700) to a single variable m,n,q, which is not a valid variable name in most programming languages.
d) mnq = 350036003700
This statement is valid. It defines a variable mnq and assigns it the concatenated value of 3500, 3600, and 3700, which is "350036003700".
In summary, statement c) is invalid because it attempts to assign multiple values to a single variable using a comma-separated list, which is not a valid syntax in programming.
