ANS:A - leads to corrosion.

Presence of sulfur in gasoline primarily contributes to increased lead susceptibility when tetraethyl lead (TEL) is used as an octane booster. Therefore, the correct option is:

• Increases lead susceptibility.

• Lead Susceptibility: Sulfur compounds in gasoline can react with lead compounds (such as those from tetraethyl lead) used as an octane enhancer. This reaction can lead to the formation of lead sulfates, which are less soluble and can deposit on engine parts. These deposits can interfere with engine operation and increase engine wear.
• Corrosion: While sulfur itself does not directly cause corrosion in gasoline, sulfur compounds can form corrosive acids in combustion products, contributing indirectly to corrosion issues.
• Gum Formation: Sulfur does not have a direct impact on gum formation in gasoline. Gum formation is primarily influenced by the presence of unsaturated hydrocarbons and oxygenates in the fuel.
• Stabilization: Sulfur does not aid in stabilization of gasoline. Gasoline stabilization typically involves additives that prevent oxidation and the formation of gums and varnishes.

The striped caecilian (Ichthyophis spp) was recently recorded for the first time in the pristine forests of Arunachal Pradesh, India, by a team of herpetologists. This discovery represents a significant contribution to the understanding of amphibian biodiversity in the region. The striped caecilian, a limbless amphibian characterized by its segmented, burrowing body, had not been documented in this part of India before, making this finding particularly noteworthy. The team's research highlights the rich and often overlooked herpetofaunal diversity of Arunachal Pradesh, which is known for its complex ecosystems and high levels of endemism. By documenting the presence of this species, the researchers have provided valuable insights into the distribution of caecilians in India and have emphasized the importance of preserving the unique habitats that support such species. This discovery not only adds to the scientific knowledge of amphibian distribution but also underscores the need for continued exploration and conservation efforts in biodiversity-rich regions like Arunachal Pradesh.
