Answer the question on the basis of passage given below :
All transition elements display typical metallic properties like high melting point, boiling point, tensile strength, high malleability and ductility, luster, etc. Their metallic character increases down the group and elements of \(4 d\) and 5d series exhibit higher metallic characters. They show variable oxidation states and forms a number of coloured compounds due to the presence of unpaired electrons which shows d-d transitions and makes them paramagnetic.
The two strongest oxidising agents among the oxides will be :
A. \(MoO _3\)
B. \(CrO _3\)
C. \(Mn _2 O _7\)
D. \(WO _3\)
E. \(VO _2\)
Choose the correct answer from the options given below:

1. A A and D only
2. B C and D only
3. C B and E only
4. D B and C only
