When the coefficient of discharge (Cd) is 0.623, then the general equation for discharge over a rectangular weir is
1.84(L - 0.1nH)H3/2
1.84(L - nH)H2
1.84(L - 0.1nH)H5/2
1.84(L - nH)H3
Answer: Option

Here we know that Franci formula:

2/3Cd(L-.1nH)(2g)^1/2 * H^3/2.

Putting the volue in this equation;
= 2/3 *.623(L-.1nH)*(2*9.8)^1/2,
= 1.8387(L-.1nH)H^3/2,
That's equivalent as;
= 1.84(L-.1nH)H^3/2.

Here, H has the power of 3/2, which is in the rectangular notch.
