d/t<85 no stiffener.
d/t 85-200 vertical stiffener.
d/t 200-250 vertical stiffener and 1 horizontal stiffener.
d/t 85-200 vertical stiffener.
d/t 200-250 vertical stiffener and 1 horizontal stiffener.

According to IS 800-1994,
Vertical stiffened d/200 should not less than but according to IS 800-71 it's d/250.
Vertical stiffened d/200 should not less than but according to IS 800-71 it's d/250.

Opt A is correct. As per code when d/t is >85 V.S are used upto 200. If d/t is > 200 HS are used.

B is correct.
No stiffeners are provided if the web is more than d/85.
Vertical stiffeners are provided if the web is less than d/85 but more than d/200.
Vertical +1horizontal stiffeners are provided if the web is more than d/200 but less than d/250 (in this case this 1 horizontal stiffener is usual to place at 2/5th of the depth of neutral axis from the compression flange).
Vertical +2 horizontal stiffeners are provided if the web is less than d/250 (in this case this 2nd horizontal stiffener is usually placed at neutral axis).
No stiffeners are provided if the web is more than d/85.

It's 180 or section will fail in shear before bucking.

Minimum D/200 max is D/85.
If the thickness exceeds d/85 then no stiffener required because. There is enough strength to carry the load as the thickness is more.
So, the minimum d/200.
