Step 1: Analyze the Visual Characteristics of the Logo
The image displays a circular corporate logo. Its primary visual elements are:
A dominant blue color forming the outer ring and background of the circle.
A distinctive, flowing "S" or wave-like symbol in the center, rendered in a bright yellow color.
This combination of blue and yellow, along with the specific abstract shape, is a unique identifier for companies in the energy or petroleum industry.
Step 2: Compare the Logo with the Known Emblems of the Given Companies
We will now evaluate each option by referencing the widely recognized logos of these prominent Indian public sector undertakings in the oil and gas sector:
(1) Gas Authority of India Limited (GAIL): GAIL's logo typically features green and blue colors, often incorporating a stylized "G" or abstract shapes representing gas flow. This design does not match the specific blue circle with the yellow 'S' or wave.
(2) Hindustan Petroleum Corporation Limited (HPCL): HPCL's logo commonly uses a combination of red, blue, and white, often featuring a stylized "HP" or a flame/star motif. This emblem is distinctly different from the logo shown in the image.
(3) Indian Oil Corporation Limited (IOCL): Indian Oil's logo is characterized by a prominent red and white design, frequently incorporating a dynamic, flame-like symbol or the "IndianOil" wordmark. This visual identity is not consistent with the logo in the provided image.
(4) Bharat Petroleum Corporation Limited (BPCL): The logo of Bharat Petroleum Corporation Limited (BPCL) is precisely identified by a blue circle containing a yellow, swirling 'S' or wave-like symbol in its center. This design is highly recognizable and is an exact match for the logo displayed in the image.
Step 3: Conclude the Identification
Based on direct visual recognition and established knowledge of major corporate brand identities in India, the logo depicted in the image unequivocally belongs to Bharat Petroleum Corporation Limited (BPCL).
