Why do the actinoids exhibit a higher number of oxidation states than lanthanoids?

Read the Passage below and answer the question:
Aldehydes and Ketones, having atleast one methyl group linked to the carbonyl carbon atom (methyl Ketones), are oxidised by sodium hypohalite to sodium salts of corresponding carboxylic acids having one carbon atom less than that of carbonyl compound is converted to haloform. This oxidation does not affect a carbon - carbon double bond, if present in a molecule.
Which of the following statements are true?

B. \(CH_3CH_2CHO\) and \(CH_3COCH_3\) can be distinguished by Fehling's test.
C. \(CH_3CHO\) and \(C_6H_5CHO\) can be distinguished by Fehling's test.
D. \(HCHO, CH_3CHO\) can be distinguished by \(NaHCO_3\) test.
E. \(HCOOH, CH_3COOH\) can be distinguished by \(NaHCO_3\) test.

Read the passage carefully and answer the Questions
Aldehydes, carboxylic acids and ketones are widespread in the animal and plant kingdoms.
They play a pivotal role in various biochemical processes of life. Their presence in nature
adds fragrance and flavor. These compounds are widely used in food products, pharmaceuticals, paints, resins and other important product industries. These compounds are prepared by various laboratory methods, which mainly include oxidation, formylation, acylation and reduction. Due to the polar nature of the carbonyl group in aldehydes and ketones, they can exhibit different reactions like nucleophilic addition. They do exhibit redox and various condensation reactions which lead to the formation of various important compounds. On the other hand, the carboxylic acids are mainly prepared by oxidation and hydrolysis of different compounds. The carboxylic acid consists of a carbonyl group and the hydroxy group (attached to the carbonyl carbon atom). This makes it possible for the carboxylic acid to participate in various chemical reactions which involve cleavage of the C- OH bond and the O_H bond along with the reactions involving the complete -COOH group.
The IUPAC name of following compound is
OHC - C₆H₄ - CHO - p

The correct sequence of steps during the corrosion of iron is
(A) Ferrous ions are oxidized by atmospheric oxygen
(B) Hydrated ferric oxide (\(\text{Fe}_2\text{O}_3 \cdot \text{H}_2\text{O}\)) formed with production of \(\text{H}^{+}\) ions
(C) At a particular spot of iron object, oxidation takes place and that spot behaves as anode
(D) Electron released at anode moves through metal and reduces oxygen in the presence of \(\text{H}^{+}\)
