Answer:
d sub level starts from the 3rd energy level; means you can see electrons in d sub level in any energy levels after third one.
So the answer is "In any energy levels ≥ 3"
A simple information ; s sub level is in any energy level,
p sub level is in any energy level beginning from the 2nd energy level,
d sub level appears ≥ 3rd energy level
f sub level appears in 4th energy level and over.
Hope it helps!

Plant cells have a cell wall, a large central vacuole, and plastids such as chloroplasts and animal cells do not have any of those
1. 12.992 L
2. 2.42 moles
3. 275.52 L
4. 567.844 g
<h3>Further explanation</h3>
Given
moles and volume at STP
Required
mass, volume and moles
Solution
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.
1. 0.58 moles ammonia :
Volume = 0.58 moles x 22.4 L = 12.992 L
2. 77.5 grams of O₂ :
Moles = 77.5 grams x (1 mol/32 grams) = 2.42
3. 12.3 mole of Bromine gas :
Volume = 12.3 mole x (22.4 L/1 mole) = 275.52 L
4. 4.8 moles iron(II)chloride :
Mass = 4.48 moles x molar mass ( 126,751 g/mol) = 567.844 g
