To estimate the sum, we can drop the hexadecimal letters and focus on the last part, which is TB2342_11. We can round up TB2342 to 1 million (10^6), and round down 11 to 10. Then the sum becomes:

11eaa948_ccdb_882b_84bc_c9ef78d7bdc7_TB2342_11 ≈ 1.1 × 10^15 + 1 × 10^10

So the answer is about 1.1 quadrillion + 10 billion, which is about 4.96. The closest answer choice is C) 4.96. Note that the other answer choices are too small or too large to be plausible estimates.
