The correct answer is:
$11 R T$
Oxygen is diatomic gas, hence its energy of two moles $=2 \times \frac{5}{2} R T=5 R T$
Argon is a monoatomic gas, hence its internal energy of 4 moles $=4 \times \frac{3}{2} R T=6 R T$ monoatomic gas, hence its internal energy of 4 moles
Total Internal energy $=(6+5) R T=11 R T$
Argon is a monoatomic gas, hence its internal energy of 4 moles $=4 \times \frac{3}{2} R T=6 R T$ monoatomic gas, hence its internal energy of 4 moles
Total Internal energy $=(6+5) R T=11 R T$
