Question

Chronologically arrange the given Satellites on the basis of their launch year. \[ \begin{aligned} A.&\ \text{IRS-1A} B.&\ \text{CARTOSAT-3} C.&\ \text{BHASKARA-II} D.&\ \text{RESOURCESAT-1} \end{aligned} \] Choose the correct answer from the options given below:

• A. A, D, B, C
• B. C, A, D, B
• C. A, C, B, D
• D. C, D, A, B

Hint:

\[ \boxed{ 1981 \rightarrow \text{BHASKARA-II} \rightarrow 1988 \rightarrow \text{IRS-1A} \rightarrow 2003 \rightarrow \text{RESOURCESAT-1} \rightarrow 2019 \rightarrow \text{CARTOSAT-3} } \] Mnemonic: “Bhaskara before IRS, Resource before Cartosat.”

Answer 1

The Correct Option is B

Concept: The satellites are arranged according to their launch years. \[ \begin{aligned} \text{BHASKARA-II} &\rightarrow 1981, \text{IRS-1A} &\rightarrow 1988, \text{RESOURCESAT-1} &\rightarrow 2003, \text{CARTOSAT-3} &\rightarrow 2019. \end{aligned} \]

Step 1: Arrange from earliest to latest. \[ \boxed{ \text{BHASKARA-II} \rightarrow \text{IRS-1A} \rightarrow \text{RESOURCESAT-1} \rightarrow \text{CARTOSAT-3} } \]

Step 2: Convert into option sequence. \[ \boxed{ C \rightarrow A \rightarrow D \rightarrow B } \] Hence, \[ \boxed{\text{(B)}} \]
